You'll have received a termination notice because you haven't paid a bill.
You can pay your bill immediately online at My BT with a credit or debit card. It's secure, quick and easy. If you pay everything you owe BT immediately, we'll happily reconnect your line within four hours of processing your payment. How long does it take for BT to process my payment? >
If a bill remains unpaid after the follow-up process, we'll issue a termination notice telling you that your line will be fully terminated unless you pay.
