Unauthorised billing

I upgraded my contract end of August. The promotional 750mb databundle I had on one of my accounts was not canceled, but instead converted into a month to month 1GB bolted onto that account at a INFLATED rate of R192 instead of R150. <br> This is besides the fact that I did not request this bolt on in the first place, and I have been struggling for over a month to get it canceled, something nobody seems able to do. <br> Over and above all that, the last timeI reported the problem I get accused of activating the blot on from the Vodacom portal site.<br> <br> In a nut shell this is what is boiling my blood.<br> 1. Stuff gets added onto my account without my consent <br> 2. I get overcharged for something I never asked for.<br> 3. I get accused by a call centre agent of activating stuff that I never did.<br> 4. Nobody is either able or willing to resolve this issue <br> 5. I am not willing to pay for something I never asked for. <br> <br> I am DONE with Vodacom
