Reason Code P08 – Duplicate Charge

Your chargeback response must include at least one of the following items:

• If multiple transactions were needed, provide documentation that shows each purchase was valid.
• If you have already processed a refund for the transaction in question, provide documentation that proves you have credited the cardholder’s account.

• If you notice a duplicate transaction, issue a credit as soon as possible.
• Double check all transaction receipts before they are deposited.
• Only send batches one time.
• If the customer wants to change to a different form of payment after initially offering the payment card, be sure to void the charge.
