Vodacom Billing for Services that I did not subscribe to!

I am struggling now for 4 months to remove a subscription from my Vodacom account that I did not sign up for. I am being send from pillar to post and each month I am being billed additionally for R1999 for something that I did not subscribe to. So many phone calls later and not to mention the emails to customer services (where the response is always - This is a TOBI query) and still no joy. Always the same story, I will log a dispute and nothing happens. I need to phone back and follow-up myself in a weeks time. And then, the result is the same ... I guess no dispute was logged as the next customer service consultant says the same over and over.
