Cancelled upgrade and contract still to be billed!!

<p>I phoned 808 to ask about upgrade - next day i phoned to cancell the upgrade , to be told that the contract can be cancelled in full the next month only. So in march i phoned to cancell, just to get billed anyhow. Middle of may after days of strugling to get through on mtn's pathetic customer service lines and not to get cut off - i again had to go through the process as it was still not cancelled!! Eventually i got a confirmation email that its been cancelled. JUST TO GET BILLED AGAIN THIS MONTH!! Been sitting with useless operators on the phone most of the day just to het transfered back and front and eventually had to phone a not free customer line - because according to them i upgraded in march?? Omy word !! I cant do this anymore ! I cant and wont pay a fee and a xtra amount of 700 rand for a ohone i cancellled of my name !</p>
