MTN

I have been with MTN since 1997. In 2010 i was given a contract where i would get 2 tickets fir a soccer gsme. After fighting over and over, i was given 1 ticket?. I renewed my contract and my phone is faulty as it does not go through external bluetooth devices. I took it back 6 times due to incorrect infirmation given to me. I was told i would have to wait 10 days for a new phone to be approved. It is the 11th day. I have heard nothing from MTN. So as a loyal, over 20 year customer, this is how I am treated? I asked the manager for a senior no. He told me there wasnt one ??????
