The customer says the item did not match the listing. Visa 13.3, Mastercard 4853, Amex C31 and Discover RM all turn on your messages with them.
What shipped matches your product page, and your messages show you offered a fix that the customer turned down or ignored.
The item really was different from the listing, or you have no record of the complaint and your reply. Then the odds are poor, and Decide will usually say accept.

Decide checks this for you on every dispute.
It reads the dispute type, checks the evidence on file against what decides it, and weighs your odds against the amount and the fees. On a filed chargeback it says fight or accept, with the arithmetic and the due date. For the ones worth fighting, Fight drafts the letter for you to send.
Check your product pages against what ships, and answer quality complaints before they turn into disputes. A documented replacement offer defeats many of these.
See when a chargeback is worth fighting, or what to do first when one arrives.
Measure is free. Decide adds a recommendation on every dispute.
