Before I sign up for this I'd like an opinion.
I'm currently on an old BT broadband contract that doesn't cap my d/l but it's only 512

thing is i'm reluctant to let it go as it's uncapped.
then today the wife is entering a comp on the BBC website and I spot an ad for these people

So I ring them and the bloke says I need to ring BT and get my MAC Code ? but not to tell BT I'm leaving but that I want it for my records otherwise they wont tell me ? Then I have to ring them back and let them have it before ringing back to tell them i'm off ?
Does this sound dodgy or is it legit ?
