So, we had a business contract with BT. Phone and broadband. Contract ended March 2018. BT sent a bill stating the account is showing a credit of £21.13 and will be forwarded to the next bill. They sent this bill every month since March 2018 even though we are no longer with BT and the company no longer exists. 15 Dec 2019 BT sends a bill for £147.83 , broadband services from 13 Sept 19 to 31 Dec 19. Phoned BT to complain and ask why they have sent this unsolicited bill to my private address only to find BT have now charges me £5 on a premium rate phone call for the privilege of complaining to them.
