POOR SERVICE

I have been an MTN customer for 15 years, approximately 2 years ago I renewed my contract, and it seems that the person responsible for capturing the details of the contract did so incorrectly. A year and a half ago I queried this error and up to today there had been no resolution. I have visited the Mtn store at pavilion on at least a dozen occasions each time waiting at least about an hour to see a consultant and they kept giving me the runaround and on many occasions I was told to give them 21 days to sort it out. I waited 21 days on many occasions. I understand that no one is gonna give me back the time that I wasted or remove the mental anguish that this has caused me. Mtn has been over billing me on my phone contract and after reporting this over a year ago they are continuing to ***** from me. Many of their staff have been rude to me even accusing me of being in the wrong on many occasions. Some of the staff were helpful, yet the problem is stil not resolved over a year later. As of today they have come back to me with an offer but still tried to rip me off until I made a fuss over it, which I really think is a slap in the face after all that I've had to deal with.
