Poor a service and empty promises

I'm so tired of vodacom after speaking to then many times about a migration that did on my contract which I didn't want and they promised to put me back on my old contract they as still billing me on the new one which is almost twice to what I was paying.Is this how this company operates forcing people to be on contracts that they can't afford? Clearly it's all about making money for them because they don't care about their clients.So I can see that you don't wanna help me just keep on *****ing my money but this year will be the last because I'm moving to Telkom when this contract expires.im tired !!!!!
