Canceling a SEPA Direct Debit payment is not possible. This is because they are forwarded to the bank and immediately included in a batch.
Refunding a SEPA Direct Debit via our system is also not possible. The reason for this is that the amount could also be reversed by the consumer. Refunding the amount could lead to the consumer receiving the amount twice. We want to protect you against that possibility. You can, of course, refund the amount into the customer's account via your own online banking environment.
