Is this a direct debit from a bank account or a recurring credit card purchase , your bank statement entry looks nothing like the DD entry on my bank statement for my BT broadband account , if it is credit card purchase rather than a DD , do they have the same DD ‘guarantee’ as far as refunds etc ?,
TBH if it is a recurring credit card charge , I didn’t know BT had that type of payment for phone/broadband/mobile , the literature usually indicates payment has to be by DD .
I’m not sure how you will be able to resolve this without anything other than the bank/credit card account number to go on , perhaps BT can search using that just that payment information , but as you have stopped future payment, presumably at some point you will be contacted by BT to say ‘we couldn’t collect this months payment’ and that email , text or letter may contain some information about the account the payment refers to .
TBH , my suspicion is for something TV related, wether it’s a mistake ( although difficult to understand how your bank/ credit card account information could be used if not by someone with access to the card number , security code on the rear etc ) or something you bought and have subsequently forgotten about .
