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> Make matters even worse I decided to upgrade another number to the same contract and that contract also has not been fulfilled as promised, on the invoice they invoiced out a fitbug that I have never received and when I asked them about know knows what I am talking about and recommend that I cancel my contract and redo it with them. Don't know what makes them think I would cancel and resign with them I would rather go to another operator who wants my business and honors their word.
