Vodacom *****ing from me

To open n contract with vodacom is easy. Cancelling is impossible. Being phoning since January. Every time i am being told that i will receive an email with confirmation. Nothing. Today again. Spent how long on the phone only to be told 3 hours later that nothing is cancelled, and that he will phone me back. Another 2 hours and nothing. Secondly this contract was a data contract 20gig fix at R301.61 per month. Nov it was R654.68 ????. Dec is R1007.76 ??. Vodacom is charging double on n monthly basis and they can not tell me why. Seems to me this is n case of ***** and somebody needs to be charged ********ly. I expect Vodacom to cancel this contract and to sort out my statements. They owe me money from last month and hopefully they will not try and take over n thousand this month for a contract that is only for R301.61. I am really sick n tired of being ********** and spending all the time on the phones. I refuse to pay all this extra money. My intention will be to open this to all me friends and there friends by means of social media to warn people about this behavior of vodacom.
