Vodacom stole money from my bank accounts!!!

You will note that this is my second review over the same issue!!! I have called Vodacom for the entire month of September telling them to cancel my contract and after speaking to over 10 *********** agents I spoke to a team leader who is clearly also *********** because she assured me that Vodacom will come and collect the sim card they had already sent to me and upon receiving their sim card the contract will be cancelled. This is on a contract which had not even commenced as it was set to commence on 01 October. I have now been billed and my account debited for a number which I don't even have a sim card for!!! So how the **** am I supposed to use the data on that number if I do not have a sim card? Why am I expected to pay for it? Why have I paid for it? the sim card was collected weeks before 01 October!!! the contract was supposed to be cancelled but it was not! this level of incompetence is truly disgusting. I want this contract cancelled immediately and I want a refund of the money you guys stole from my account!!
