Close ur account FTW..
Always works..
It did for a colleague at work who closed his account before Christmas.
This was followed by the usual "what can we do for you to make you stay" calls.
Answer - free upgrade please.
"Sorry sir, that isn"t an offer at present"
"Okay, close the account please"
Call after call asking him to return until suddenly there was an offer of free box, free installation, etc.
He had it installed last Friday.
