Vodacom ******

Hi, I was about to finish my contract and I got a call from a guy from vodacom online. He persuaded me to take another contract and I made it clear to him that I needed to finish my contract and just breath a sigh of relief after finishing paying for one of my contracts. My mistake was to give him a chance to talk to me further. I said categorically to him that I will decide once I have finished paying for the current contract. On 1 October I discovered that a Sim contract was loaded to my account and since then I have been phoning vodacom trying to cancel this unwanted contract. I have phoned vodacom more than 20 times and I have been put to different departments I have spoken to many people there and they all promise to help with the cancelation but nothing happened up to now. I have been given different reference numbers for my issue and it makes no difference. To me vodacom are just plain ****** and *******. I have paid R1034 on the 15th including the money for this unwanted contract. I am writing to helopeter because I have tried everything but without any success. I believe that vodacom has that rule among its workers of frustrating a customer until you give up. All I need is to cancel this unwanted contract. Can't wait to change this service provider. I thought they were the best until I was ******* or ****med into a contract that I don't need. Who in his right mind would opt for a contract that is way above than what I was paying before.
