Chargeback Guide 2026: Get Your Money Back from Temu, Shein, AliExpress

Q: How do I get a refund from Temu if they deny my claim?

If Temu denies your refund: (1) Escalate within the Temu app, (2) File a complaint with the FTC at reportfraud.ftc.gov, (3) File a chargeback with your bank using Visa 13.1/13.3 or Mastercard 4853, (4) Submit forensic evidence of the original product listing.

Q: Can the online store fight my chargeback?

Yes, merchants can file representment with counter-evidence. A forensic evidence package with blockchain timestamp is difficult to contest because it proves what the page contained at purchase time.

Q: Why are plain screenshots rejected in 2026?

In the AI era, images can be edited in seconds. Banks treat screenshots as unverifiable. Forensic evidence with SHA-256 hash and blockchain timestamp is mathematically verifiable and cannot be forged.

I. The $800 "Waterproof" Phone That Wasn't

Sarah, a freelance photographer from Austin, TX, bought a flagship smartphone in October 2025. The product page clearly stated: "IP68 waterproof — safe for underwater photography up to 6 meters." That's exactly why she chose this model for her upcoming beach vacation.

Three weeks later in Hawaii, she dipped the phone just 2 meters underwater for 30 seconds. The screen flickered and went black. Water damage. Phone dead.

When Sarah filed a warranty claim, it was denied. The response: "Our product description clearly states the device is splash-resistant only. Submersion voids the warranty."

Sarah checked the product page. The description now read: "IP68 splash-resistant — not suitable for underwater use." The "underwater photography" claim had vanished. Without proof of the original description, she had no case.

The Disappearing Description Problem

Online retailers can change product descriptions at any time. Unlike paper receipts that document what you bought, e-commerce purchases often link to dynamic pages that can change after your transaction. Your order confirmation shows the price — but rarely the full technical specifications that influenced your decision.

This isn't a hypothetical scenario. It happens to millions of consumers every year, and the scale of the problem is staggering.

II. Real Lawsuits: When Companies Got Caught

While individual consumers often lose these battles, class action lawsuits have exposed systematic deception by major brands. These cases reveal a pattern: companies advertise features to sell products, then hide behind warranty exclusions when those features fail.

Sony Xperia Class Action

A class action lawsuit alleged Sony sold mobile devices that were "deceptively marketed as waterproof." Sony's marketing showed phones being used underwater, in pools, and in the rain. But when devices failed from water contact, warranty claims were denied.

Sony's Settlement Terms:

Extended warranties for owners of affected devices
50% MSRP compensation for customers whose claims were denied
Mandatory changes to labeling, packaging, and advertising
Sony agreed to modify use of terms like "waterproof," "water-resistant," and similar claims

Apple iPhone Water Resistance Lawsuits

Multiple lawsuits targeted Apple's water resistance claims. In November 2020, Italy's competition authority (AGCM) fined Apple EUR 10 million for misleading consumers with water resistance advertising while denying warranty claims for liquid damage.

"This means consumers standing at the edge of a pool or ocean whose devices get splashed or briefly submerged are denied coverage because the water contained chlorine or salt."
— Class action complaint, Zouzout v. Apple Canada Inc.

FTC vs. Temu (2025)

In September 2025, the FTC ordered Temu to pay a $2 million civil penalty — the first-ever enforcement under the INFORM Consumers Act. The case centered on Temu failing to provide consumers with mechanisms to report suspicious marketplace activity.

What Is "Bait and Switch"?

Bait and switch is a deceptive marketing practice where a seller advertises a product with certain features to attract customers, then reveals limitations after the sale or substitutes the product with something different. In the digital era, this often involves changing online product descriptions after purchase.

III. The 337-Million Chargeback Problem

Answer: In 2026, approximately 337 million chargebacks are expected worldwide, up from 238 million in 2023 (Mastercard/Ethoca data). E-commerce chargeback rates surged by 222% between Q1 2023 and Q1 2024 (Sift Digital Trust Index). The average dispute costs $190 to process.

Chargeback Reason Codes: The Terminology You Need

Critical: When filing a chargeback, you must use the correct terminology. Otherwise your claim gets automatically rejected by the bank's algorithm — before a human ever sees it. Bank chargeback systems filter claims by reason codes and keywords.

Network	Code	Description	Required Evidence
Visa	13.1	Merchandise/services not received	Proof of purchase, tracking info, delivery confirmation
Visa	13.3	Not as described or defective	Comparison of original vs. current description
Mastercard	4853	Goods/services not as described	Documentation of original listing
Amex	C31	Goods/services not as described	Proof of original product claims
Discover	RM	Cardholder disputes quality	Documentation of original advertising

The Critical Point: The Original Version of the Website

Always submit the original version of the website to your bank — before the seller changed it. Without this evidence, it's your word against the merchant's server logs. The bank will almost always rule in the merchant's favor if you can't produce the original documented version.

Dark Patterns: Fake Scarcity and Dynamic Pricing

Modern e-commerce uses psychological manipulation tactics that ProofSnap can expose:

Fake scarcity: "Only 2 left in stock!" when thousands are available. Capture the page today and again tomorrow — if the count resets, you have proof of deceptive practices.
Dynamic pricing: Prices change based on your browsing history, location, or device. Capture before and after to document discriminatory pricing.
Disappearing discounts: "50% off — ends in 2 hours!" that magically reappears every day. A series of timestamped captures proves the pattern.
Bait pricing: The advertised price differs from the checkout price. Capture both pages to document the switch.

IV. The 2026 Reality: Why Screenshots No Longer Work

Answer: Why are screenshots rejected as evidence in 2026? In the AI era, images can be manipulated with tools like Midjourney, DALL-E, or Photoshop AI in seconds. Banks and dispute processors increasingly treat screenshots as "unverifiable." Valid digital evidence now requires: (1) SHA-256 hash (cryptographic fingerprint), (2) Blockchain timestamp (immutable), (3) TLS certificate verification (source authentication). This combination mathematically proves content authenticity.

The Problem

AI can edit any image in seconds. Prices, descriptions, specifications — everything is manipulable.

The Result

Banks and dispute processors increasingly reject plain screenshots as "unverifiable."

The Solution

Cryptographic fingerprint (SHA-256 hash) + immutable blockchain timestamp = forensic evidence.

V. Why the Wayback Machine Isn't Enough

Answer: The Wayback Machine is not reliable legal evidence. In Weinhoffer v. Davie Shoring (2022), a US appeals court ruled it "does not rise to the level of a source whose accuracy cannot reasonably be questioned." Courts often require expert testimony from Internet Archive employees to verify Wayback Machine evidence — impractical for consumer disputes.

"The private internet archive does not rise to the level of a source whose accuracy cannot reasonably be questioned."
— US Court of Appeals for the Fifth Circuit, Weinhoffer v. Davie Shoring, No. 20-30568 (2022)

Not automatically admissible: Courts don't automatically accept Wayback Machine screenshots as reliable evidence
Requires expert testimony: In the Gasperini case, the government had to produce testimony from an Internet Archive employee to verify records
Incomplete coverage: The Wayback Machine doesn't crawl every page every day. Your specific product page on your purchase date may not exist
No accuracy guarantee: Pages can be excluded by robots.txt, JavaScript-rendered content may not be captured, and there are time gaps

VI. Your Legal Rights

US Consumer Rights

Key US Consumer Protections:

Fair Credit Billing Act (FCBA): Gives you the right to dispute billing errors, including charges for goods not received or not as described. File within 60 days of the billing statement.
FTC Act Section 5: Prohibits unfair or deceptive acts in commerce — bait-and-switch practices violate federal law
Regulation E (Debit Cards): Provides similar protections for debit card transactions, though with tighter deadlines
State consumer protection laws: Most states have "Little FTC Acts" with additional protections — California, New York, and Texas have particularly strong statutes
Chargeback rights: Card networks (Visa, Mastercard) provide chargeback mechanisms independent of federal law, with 120-day filing windows

UK Consumer Rights

Key UK Consumer Protections:

Section 75 of the Consumer Credit Act 1974: For credit card purchases between GBP 100-30,000, the card issuer is jointly liable with the seller. This is stronger than a chargeback — it's a statutory right.
Consumer Rights Act 2015: Goods must be as described, of satisfactory quality, and fit for purpose. 30-day right to reject; up to 6 years for claims.
Chargeback (Visa/Mastercard): Available for debit cards and credit card purchases under GBP 100. No statutory basis but enforced by card networks.
14-day cooling-off period: For online purchases, right to cancel without reason under Consumer Contracts Regulations 2013.

How to Dispute Purchases from Temu, AliExpress, or Shein

When you buy from Chinese marketplaces (Temu, AliExpress, Shein, Wish), your legal options change dramatically. US and UK consumer laws have limited reach — good luck suing a warehouse in Shenzhen.

Warning: Chinese Platforms and Consumer Compliance

Consumer organization Euroconsumers found that 66% of Temu products and 73% of Shein products fail to meet European regulations. In September 2025, the FTC fined Temu $2M under the INFORM Consumers Act.

The US Consumer Product Safety Commission (CPSC) has also launched investigations into Shein and Temu over safety concerns.

Your only realistic remedy is a chargeback through your bank or credit card issuer. And here's the critical insight: your bank doesn't care about US or Chinese contract law. What they care about is evidence.

Insider Tip: The 70% Rule with Chinese Platforms

Chinese platforms often argue disputes with their internal records — "our logs show the description was correct." This tactic works on most customers.

But: When you upload a ProofSnap PDF report with full metadata (SHA-256 hash, blockchain timestamp, TLS certificate) into the dispute, platforms refund immediately in about 70% of cases. Why? Because they know they can't win against forensic evidence in a bank chargeback.

The cost to the platform of a lost chargeback (fees, reputation damage with the card network) far exceeds the value of the item. It's cheaper for them to give you your money back.

VII. How to Build Legally Defensible Evidence

Element	Plain Screenshot	Forensic Package
Timestamp	No: EXIF date can be edited	Yes: Blockchain timestamp (immutable)
Integrity proof	No: File can be edited	Yes: Cryptographic SHA-256 hash
Source verification	No: Could be from any source	Yes: URL, TLS certificate, server metadata
Full page content	No: Only visible area	Yes: Complete HTML + extracted text
Tamper protection	No: Vulnerable to Inspect Element	Yes: HTML hash validates visual content
Legal admissibility	No: Easily challenged	Yes: eIDAS 2 compatible

A Screenshot Is a Lie. Metadata Is the Truth.

In 2026, AI can generate or edit any image within seconds. A screenshot (pixels) proves nothing — it's just an image anyone could create with basic tools.

What can't be faked is the TLS certificate digital signature from the server. When ProofSnap captures a page, it records the cryptographic handshake with the server — proof that you connected to the real temu.com or amazon.com at that specific time.

This is the moment the online store's legal team backs down: they can claim "the screenshot was manipulated," but they can't claim their own server's TLS certificate was forged. Math doesn't lie.

VIII. Pre-Purchase Evidence Checklist

Before and during every significant purchase:

• Capture the product page with a forensic tool before completing the order
• Scroll through all specifications — capture the entire page, not just the visible area
• Capture any ads or claims that influenced your purchase decision
• Save confirmation emails and receipts immediately
• Capture the Terms & Conditions — stores change those too, not just product descriptions
• Capture the checkout cart right before payment — document the final price including all fees

The First Email That Makes Online Stores Back Down

Consumer protection specialists report that most disputes are won or lost in the first communication. Include this sentence in your first complaint email:

"I have a forensic evidence package with blockchain timestamp from the date of purchase that documents the original product description, specifications, and terms. I am prepared to submit this evidence to my bank for a chargeback under Code 13.3/4853 if we cannot resolve this dispute directly."

This one sentence signals that you're not bluffing, you know the process, and escalation will be painful for them. Many sellers "find a solution" immediately rather than face a documented chargeback that affects their merchant account rating.

How to Submit Evidence to Your Bank (Cover Letter)

Banks don't reject chargebacks because consumers are wrong — they reject them because people submit 50 unorganized files. Structure your submission like this:

Cover letter (1 page): State dispute, amount, date, and reason code. Summary in one paragraph.
ProofSnap evidence PDF: Capture of the original product page with timestamp and SHA-256 hash.
Current page capture: Screenshot or capture showing the changed description.
Order confirmation: Proof of purchase with date and amount.
Communication log: Your complaint to the seller and their response (if any).

Copyable cover letter template:

Subject: Chargeback Request - [Code 13.3/4853] - Order #[ORDER NUMBER] Dear Dispute Resolution Team, I am filing a chargeback for $[AMOUNT] charged on [DATE] by merchant [MERCHANT NAME]. The product received does not match the description at the time of purchase. Attachments: (1) Forensic capture of the original description with blockchain timestamp, (2) Current description showing the change, (3) Order confirmation. Evidence integrity verified via SHA-256 hash and Bitcoin blockchain timestamp (see .ots file for independent verification). Sincerely, [YOUR NAME]

IX. How to Win a Chargeback: Step-by-Step

How to file a chargeback with your bank: (1) Contact your bank by phone or online banking, (2) Fill out the dispute form with reason "item not as described," (3) Attach evidence: order confirmation, seller communication, forensic capture of original listing, (4) Specify Code Visa 13.3 or Mastercard 4853. Deadline: 120 days from transaction. The chargeback is generally free for consumers.

Step	Action	Why It Matters
1	Attach evidence.pdf from your ProofSnap capture to the chargeback claim	The bank sees a certified document with metadata, not just an image file that could have been created
2	Add technical note: "Integrity verified via SHA-256 hash and Bitcoin blockchain timestamp"	Prevents automatic rejection; signals evidence meets forensic standards
3	Show before/after comparison: Original capture vs. current product page	Visual proof of description change — irrefutable evidence of deception
4	Select the correct reason code: Visa 13.1/13.3, Mastercard 4853, Amex C31	Matching evidence to reason code dramatically increases approval rate
5	Meet the deadline: File within 60-120 days of purchase (varies by card network)	Late submissions are automatically rejected regardless of evidence quality

Warning: The Seller Will Fight Back (Representment)

Many consumers underestimate that merchants actively fight chargebacks. The process is called "representment" — the seller submits counter-evidence and often claims:

"The customer misunderstood the description"
"The specifications were clearly stated"
"Our records show the correct description"
"The customer already used the product"

This is where ProofSnap becomes your "certified witness": The merchant can claim whatever they want — but they can't claim your blockchain-verified evidence of the original page is forged. The forensic capture documents exactly what was on the page at the time of purchase. That beats every "the customer misread it" defense.

Frequently Asked Questions

How do I get a refund from Temu if they deny my claim?

If Temu denies your refund request: (1) Escalate within the Temu app by contacting support again and referencing their 90-day return policy, (2) File a complaint with the FTC at reportfraud.ftc.gov, (3) File a chargeback with your bank using Visa 13.1 (not received) or 13.3 (not as described) / Mastercard 4853, (4) Submit forensic evidence of the original product listing. With proper evidence, most chargebacks against cross-border merchants succeed.

How long does a chargeback take?

The chargeback process typically takes 45-90 days. Your bank has 30 days for initial review. If the merchant contests (representment), the process can extend further. You often receive a provisional credit within 10 days, but this can be reversed if you lose.

Does a chargeback work with PayPal payments?

Yes, but with differences. First use PayPal Buyer Protection (180-day deadline). If PayPal rules against you, you can still file a chargeback with your bank (if you paid via card through PayPal). Note: PayPal may restrict your account for repeated chargebacks.

Can the online store fight my chargeback?

Yes, merchants can file "representment" — an appeal with counter-evidence. That's why your evidence is critical. A forensic package with blockchain timestamp is difficult to contest because it proves what the page contained at the time of purchase. A plain screenshot is easily challenged by the merchant.

Is filing a chargeback free?

For consumers, chargebacks are generally free. Some banks charge a fee for unsuccessful chargebacks (typically $15-50), but most major US and UK banks don't charge. The merchant pays $15-100 per chargeback — that's why they often prefer to settle directly.

What's the difference between a chargeback and a Section 75 claim (UK)?

Chargeback: Card network process (Visa/Mastercard rules), available for all card types, no minimum amount. Section 75: UK statutory right for credit card purchases GBP 100-30,000 — the card issuer is jointly liable with the seller. Section 75 is stronger but only applies to credit cards. Use both: file a Section 75 claim AND a chargeback simultaneously for maximum leverage.

Why are plain screenshots rejected in 2026?

In the AI era, images can be generated or edited in seconds. Banks and dispute processors know this — they increasingly treat screenshots as "unverifiable." A forensic evidence package with SHA-256 hash and blockchain timestamp is mathematically verifiable and cannot be forged. That's the difference between rejection and success.

Can I file a chargeback for a Temu purchase I made with a debit card?

Yes. Debit card chargebacks are covered by Regulation E in the US. The process is similar to credit cards but deadlines are tighter — report within 60 days of the statement date. Visa and Mastercard chargeback rules apply regardless of whether you used credit or debit. However, credit cards offer stronger protections (FCBA in the US, Section 75 in the UK).
