I managed to speak to someone late yesterday afternoon and he pretty much confirmed what you say.
I say pretty much because it seemed like a bit of a mystery to him, he said he'd been working for BT for years and had never seen that happen before.
He said he would suppress any future billing notifications meaning that bills for £0.00 would continue to be raised but I wouldn't be notified of them.
Seems a strange solution to me but I'll see how it goes.
