Why can't I cancel a 'SEPA DD'?
Once a SEPA Direct Debit (SEPA DD) has completed you are able to use your SEPA rights to cancel a SEPA direct debit.
How will I know it is complete?
When a Direct Debit direct first presents on your account you will see "SEPA DD" with no other information. Once the direct debit completes it will include some information about the originator such as "ABC SEPA DD".
