MTN no TCF THEY JUST DON'T CARE

I'm really starting to regret ever signing up with mtn. I have 3 contracts with them paying over a thousand rand and the treatment I'm getting is the pits. I've been with them for years now and really regretting renewi renewing my contracts. I have a new contract which started last month and I have been having one problem after another with it. The service levels are non existent any more. This is a data sim they were supposed to top up my sim last week and they haven't. I called them and they simply told me a "ticket has been logged it will take 3-5 working days." no apology for the inconvenience caused, no matter of urgency nothing at all, no body cares. I don't think I want the stupid data to be loaded any more. I need this contract canceled asap with no cancelation fees due to them as a form of TCF. I haven't been treated fairly from the start so I'm better off without you MTN. Please cancel this new contract and I'm not a cent to you!
