Crumbs... that is a total nightmare... seems that BT have little regard for customers, only kit and ensuring updates are carried out. As for disabling the kit from being able to be used with another ISP, that's just ludicrous and stupid. I've never really understood why mobile phones are locked to a provider, other than to protect the provider and ensure that users are forced or 'locked into' the provider. Kinda smells of fear and insecurity if you ask me.

Clearly, BT want their Talk package to only work on their network - again bizarre.

I still hate the nights of being kicked off, even momentarily. It's just bad manners.

I'm sorry to hear of your ordeal, I'm confident you aren't alone here.
