My bil would go up by around 40%, i've sent my letter in (2 weeks ago) and had acknowledgement that they have got the letter, but nothing since. I rang up customer service yesterday and he seems to believe my contract will be cancelled and my PAC code sent out but I have to wait until the letter comes through telling me exactly whats going to happen.

Telling me?? I'll tell him... I am cancelling, and i'm keeping my phone and ... thats pretty much it!!
