Contract cancelled but still getting billed

Hi There<br> <br> I entered into a contract with Vodacom over two years ago which was supposed to have ended early this year around April, but it was converted to month-to-month contract without being asked about it. I did pay up until mid August I cancelled the contract which was supposed to have ended 20October but and I was supposed to have been billed R20.00 for the premature cancellation in August plus the contract fee. That did not happen instead Vodacom kept billing me the same amount. I thought maybe end of November it will be cancelled as I did not get the monthly airtime I always got.<br> <br> Instead I was slammed with a bill of R318.00 but the sms I got a few days before said that I owe R100.99m, called Vodacom to verify the info and to understand why the contract was not coming to an end I was told I am owing R318.00 three times more than what the sms said. I fought with the consultant that was assisting me because I did not understand why the huge amount. She tried to explain but I just did not understand why the huge amount. Now today the 15Dec I got a statement of R438.97 in a space of few days to a week since my last call. My phone is blocked but I get a huge bill?Day *******!
