Consumer Disputes
S02 Reviewed Support; Will Not Be Debiting Account
Details
American Express reason code S02 indicates that Amex has reviewed the documentation submitted by the merchant in response to a dispute and has decided not to proceed with a chargeback. This means the merchant’s evidence was deemed sufficient, and no funds will be debited from their account.
This reason code is essentially a resolution notification in the merchant’s favor. No further action is required, but it’s a helpful confirmation that the case has been closed successfully based on the support provided.
