Not honouring contract/terrible service

In May I phoned to cancel my contract as MTN was offering a better deal and I was out of contract. After going through to the retentions department I was promised minutes and data to match the deal offered at MTN. Now in the 1st month of the new contract I have been told my limit has been reached and this is because everything they had promised to be added onto my contract HAS NOT been done and I have already been 3 days without being able to make calls. When I called them I was told I would have to wait up to 7 days for this to be resolved....unbelievable still 3 days in I haven't heard one thing from vodacom who if knows if they are sorting it out. QUICK TO PROMISE, SLOW TO DELIVER<br> Here I am weeks after being promised that this will be investigated, never once contacted by phone but sent an email last week stating this had been sorted but when I phone the customer care line it still has not been fixed. This is ridiculous if you cant deliver what you promise, cancel both my contracts refund me for the minutes and data I have not used due to your incompetence and I can move to a service provider who wants my business and can honor their promises.
