The cardholder states they shouldn't have been charged because they already cancelled the transaction.

Show that the chargeback is either remedied or invalid. Either by displaying that the transaction was not a recurring transaction, the transaction was recurring and the cardholder failed to meet the cancellation terms of the signed contract, documentation that services are being provided to and used by the cardholder after the cancellation date, or documentation that proper disclosure of entering into the recurring transaction was provided to and accepted by the cardholder.
