Since the replacement of domestic direct debits with European direct debits under the SEPA directive, mandate management is no longer carried out at the bank, but rather by the creditor.
To permanently cancel a direct debit, you must therefore contact the creditor.
However, it is possible to block a direct debit. Open the list of direct debits on Web Banking, under “Payment”. Then, click on the direct debit you want to block. Click on “Block direct debit”.
