Re: Direct Debits.Only YOU can set up a direct debit on your account Ffosse. Talk Talk does not have access to your bank account. If there is a direct debit then YOU must have at some point given authority for that either by signing a piece of paper or doing the same online.
Re: Direct Debits.Once you cancel it with the bank if they do try again the bank will be at fault letting them have any money so it's a really safe system as no bank wants a reputation of ignoring a customers orders.
Re: Direct Debits.There is no problem cancelling a direct debit (unless it is part of a contract you have agreed to). If you need to cancel as well as cancelling with your bank (either on line or personally) you must also advise the recipient that you have or will be cancelling the DD and on what date it will become effective.
