Vodacom Cancellations

After my previous review to Vodacom, they tried phoning me while I was in a meeting and couldnt take a call, I responded to their message to say I couldnt take the call. I phoned them again today. After they said they will send me my contract< I received a sms to say the contract was sent but I never received anything. My statement shows a 24 month contract and this is the end of it, I want to cancel it. Number ********** 687. When I phone customer care they tell me I can cancel it but put me through to cancellations to cancel it and then they tell me this is a 36 month contract. I did this upgrade over the phone, that time I never received any quote or contract or nothing from Vodacom. Now they want to send a quote to say its a 3 year contract, this is not acceptable. I phoned probably 4 times already to find out when I could cancel this as I took this contract out for someone else. When speaking to cancellation agent she told me I had to request a contract when taking out a contract, since when do you have to request something like this? Now I received a sms to rate the experience I had, a soon as I give them a bad rating, I get a sms back to say you have entered an incorrect response, that means Vodacom is manipulating their ratings. I have been with this company for ages and never had such a bad experience.
