If you're trying to do a refund, and you get the error message "Transaction does not exist", it is because the transaction was not recent enough for the refund to be issued. Typically, the transaction loses the credit card token if it has passed a certain amount of time, which varies by merchant processor. Check the date of the transaction. It is usually not a recent one, when this happens. You will need to contact your merchant processor to issue the refund.
