@Angeljoel, One Touch Switching has only recently [12th September 24] come into practice for switching to full fibre from other companies.
It's highly likely that Talktalk's billing system doesn't know that you left if you didn't call them directly yourself.
03451 720088 after 9am.
Even if it's been processed correctly and you told them etc, it takes a while for billing to stop because at that time, if the new company didn't get in touch, you'd have to give 30 days' notice yourself. Billing doesn't just stop when out of contract. It rolls on at full price.
It can then take another month after the cease, if it's come into effect, to sort out billing which is not likely to be on the same cycle as your cease / end of contract date. You will eventually get a bill for £0.00, and only at that stage is it safe to stop the DD.
Check the details of the cancellation process in the subsections in this article:

I'll move this to the billing section for you for staff attention.
