What Visa 13.3 means
Visa 13.3, "Not as Described or Defective Merchandise/Services", is used when the cardholder says what they received didn't match its description, or didn't work.
On Stripe the dispute shows the reason Product unacceptable, with 13.3 as the network reason code. Visa 13.5 (Misrepresentation) falls under the same Stripe reason.
Why digital customers file it
- The product didn't do something they assumed it would.
- A course was shorter, more basic or different from what they expected.
- A bug or outage stopped them using it for a while.
What wins it
- The product description as presented at checkout: features, contents, what was included.
- Evidence they used it, which often contradicts "it didn't work" or "unusable".
- Your refund policy, and whether the customer asked for a refund under it before disputing.
- Your replies to any complaint, showing you tried to resolve it.
A customer who never contacted you before disputing is a useful point: it shows they chose a dispute over the refund route you offered.
When to accept
If the product really didn't match what checkout promised, or an outage meant they couldn't use what they paid for, accepting or refunding is usually right.
Every Stripe evidence field and the file limits are in the Stripe dispute evidence guide. For the reason as a whole, see Stripe "Product unacceptable" disputes.
FAQ
What's the difference between Visa 13.3 and 13.5?
13.3 says the product was not as described or defective; 13.5 says it was misrepresented. Stripe files both under Product unacceptable, and the evidence is largely the same.
Does my refund policy help with a 13.3 dispute?
Yes. Showing the policy the customer agreed to, and that they didn't use it before disputing, supports your case.
