@JohnC2 thank you for the update.
All, if reading this as you are leaving BT yourself, or via a new Supplier, and looking to avoid bad credit records and court actions: Ideally, drop your BT Mail if you can when asked, as it complicates your exit (requires a new account setting up and a migration). Once you have your end date or cut-over, keep a check on MyBT ‘Your Products’ to see they go grey on the date. Start chasing if not.
If searching due to a missing Final Bill problem 7 days after cut-over or exit - my solution, having tried various calls/chats/complaints:-
The best method to get to a knowledgeable person who may know enough to fix it: web-chat Account & Billing.
The best method to get attention for oversight in BT: raise a Customer Complaint about Billing, that you are receiving Recurring Bills for services you have no longer Contracted for, in contravention of your Consumer Rights. Until you get your Final Bill the Complaint is not resolved for you (BT Staff will likely see an explanation for the delay as sufficient resolution), so check regularly that the Complaint hasn’t been closed and reopen it when it has been.
