Other way round
I was having problems with the adsl from Orange. Kept phoning the nice (and remarkably informative) chaps in Mumbai. They could not seem to do anything their end. On the fifth call, the chap suggested I phone up the accounts number and ask to cancel the service. I didn't especially want to leave, they are all the same in the UK basically, but I did phone. I got asked why I wanted to leave, told the (obviously UK based) account staff member about the problem (capped connection speed) and the five phone calls.
Miraculously, original problem sorted in a day.
