Terrible customer service

I would like to express my extreme dissatisfaction with MTN since I joined at the end of April. MTN has overcharged me twice in the months of June and July for out of bundle fees I did not once agree to when purchasing my contract.

When I called the customer centre I given the run around. I would like this issue rectified immediately please and I would like these amounts to be refunded as this is not what I signed up for. It has now been months later, I have called and sent numerous emails to MTN complaints and none of this has been rectified.
