Cancellation of Contract

I am struggling to get a contact of R60 cancelled for 3 months now with no luck. I phone in the beginning of August to cancel this contract and I was told it will be cancelled ... just to see it's still on the my account the next month. Then I phoned about 3 - 4 times again but with no luck. I was at one stage told that I cannot cancel this contract because it was upgraded. I DID NOT UPGRADE THE CONTRACT .... I WANT IT CANCELLED!!!!!!! How difficult can it now be. This contract still shows on my statement which must be paid by the end of November. I don't know what to do anymore ... It's only R60 but why must I pay for something I don't use and someone else benefits from it.

I'm really GATVOL for Vodacom. I wish I could cancel all my contracts. I'm sick and tired of their bad service.
