Vodacom stole my Money

I was debited a total of R1024.89 by vodacom and this is not for the first month and I have no relation whatsoever with vodacom, I escalated the issue and apparently I was told that I opened a contract in January and I was told that If i didnt open a contract I should get an affidavit stating that I didnt open a contract. I then refused and requested for all the information they collect when they were supposedly opening this contract and I was told that they were not able to give me. I refused because I am punished for their lack of controls of ensuring a contract is not opened under a false name. This is why I never associated myself with vodacom in the first place because of the appalling services and their ridiculous prices.
