Shocking service from MTN

When applying for a new SIM card from MTN for my work phone I was promised an 083 number, which I did not receive. We were told we would have to pay R250 to change the number, which we refused to pay. When receiving my SIM in Jan I had no data or SMS's. My contract is MTN MYCHOICE 500, which includes SMS' data and minutes. I only received minutes. At the start of February I didn't receive any minutes, data or SMS'. I went into an MTN store whereby the lady had to hold for 5 hours to speak to another representative from MTN to ask why I hadn't received all these things. Eventually they told her I would be receiving the minutes. I then only received data and SMS'. It's February 16th and I enquired about this 1st February. The lady from the MTN store has been calling nearly every day since that, holding for 5-6 hours at a time trying to get my minutes loaded. They keep telling her I will receive it and I haven't. Today I was told there was a fault with my contract and it will take MTN 28 days to sort the problem. This is completely unacceptable and whats even better is the store members suggested that the only way we could sort this problem quickly is by complaining on Hello Peter.
