VODACOM UPGRADE INCORRECT!!!!

I have been a Vodacom customer for years now. I was due for an upgrade and went to the branch to check what deals Vodacom has, after that I went to another service provide to find out what they offer. The other service provider gave me a much better contract than Vodacom could provide me. So I phoned Vodacom to cancel my contract, the cancellation department consultant said that she can provide me with the same contract. So I agreed to the contract. Long story short the consultant delivered the incorrect phone and after a lot of calls to the call centre and managers assisting it came to my attention that the contract on their system does not agree to what we agreed to over the phone. The consultant said that she did not make a mistake and that I am wrong. What Vodacom is not telling you is that it’s so much hassle to get hold of the recordings and for quality control to listen to the conversations between you and the consultant to provide you with the contract that I agreed upon. Vodacom still haven’t picked up the incorrect phone nor did they follow up with the quality control to provide me with the recordings. I cannot move to another service provider if my contract is not cancelled. This cost me so many days without a phone and could have cancelled my contract weeks ago and got a new contract with another service provider. Because I’ve exceeded the number of phone calls to the call centre I cannot follow up, so I’ve mail the customer care. They see it as a new case and I need to wait another 7 days for them to sort out everything.
