Appalling service from vodacom

A few months ago vodacom phoned me and offered me an upgrade, no phone and lot more expensive. After negotiating with the company they offered me a contract which seemed reasonable. It was put in place telephonic ally and I received my minutes, data and smses according to the contract. About 6 weeks later everything was taken away, from me, having 114 minutes, 1.64 gigs of data and 595 smses, suddenly gone, had absolutely nothing. After numerous calls to them and their upgrade department, I have yet to have a response. I called on their gateway branch, one lady there said she will sort it out, what happened with me was not uncommon, in fact it happened frequently. This was about two months ago. To date, absolutely no response. I have been there a few more times, they promise to escalate it, I have even received smses to say it's been escalated, but still nothing. The service is appalling to say the least, I don't recall ever being treated so shabbily. I want my contract sorted out but I am at my wits end. Noone at vodacom cares, what they have done to me smacks of totally ********* behavior. I will never enter into a contract with them and I will tell everyone about this disgusting state of affairs.
