Never ever take a contract with vodacom

Mondo, on Vodacoms orders, called me to upgrade my contract. The agent explained the upgrade, I asked whether it includes minutes and she said yes. She also said that I will be receiving a copy of the contract (via email or sms) that I will sign and if I do not sign then it will not be valid. I have 48 hours to sign it. I received no contract to sign but it was actioned and my contract was upgraded on vodacoms systems. Further, what I am receiving each month, is not what the agent discussed. I have requested a copy of the contract, vodacom said I must go in store to hear the call. But, if I am not happy with what I hear and I want a copy, I cannot get a copy; I have to get a legal team to request it. I have been with Vodacom for 20 years and I will not spend another month with them from this point forward.
