Cancelling a vodacom contract: Is it impossible?

I am trying to cancel a contract. I went to the Vodacom Shop in Eikestad Mall on where I was informed that I have to phone ***. When I phoned this number and followed the prompts, I was informed by the computer that the option(no 2), cancellation of contracts, was not available. I was refered to the website, www.vodacom.co.za. There I communicated with a "bot". Who then said I should send an email to ***. I have had no response.

I want to cancel this contract: number ***. Account number I***-6. Last year it took me more than 3 months to cancel a contract - purely, because there is no responsiblity delegated to the branch level. I believe that Vodacom is quick to give contracts and very, very slow to cancel them once the time period is expired.
