I hate

t mobile. such utter c*nts, i told them a month ago i wanted to cancel the contract and now they have no record of it so will try to charge for another month of line rental for a phone i havent even used!

I remember always having to tell t-mobile everything twice cause they forget to listen to your request the first time. It took them three months to restart a direct debit i'd never asked to cancel, while sending me loads of snotty letters about over-due bills during that time.
