• Incorrect transaction code - You sent a transaction with an incorrect transaction code (i.e. you meant to send a credit, but you actually sent a sale, or you meant to process a sale and sent a credit).
• Late presentment - The transaction was completed past the required time limits.
• Incorrect currency - You sent a transaction that was processed with an incorrect currency code or one of the following: (a) the transaction currency is different from the currency transmitted through the card brand; (b) the cardholder was not advised or did not agree that Dynamic Currency Conversion (DCC) would occur.

• Duplicate processing - The cardholder claims that a single transaction was processed more than once.
• Merchandise/services not received - The cardholder claims that merchandise or services that they ordered were not received or that the cardholder canceled the order as the result of not receiving the merchandise or services by the expected delivery date (or merchandise was unavailable for pick-up).
• Canceled recurring - A recurring transaction was processed after it was canceled or the cardholder’s account was closed.

• Credit not processed - The cardholder’s bank received a notice from the cardholder claiming that they received a credit or voided transaction receipt that has not been processed.
