MTN NO SERVICE PROVIDER

I don't know what is going on with MTNSA as of late. I have been a customer of theirs for about 15 years & have never received such terrible service as I have of late.

A person cannot upgrade, cancel or receive a refund without having problems. The "Contracts Customer Care" department is unreachable most of the time and when one finally does reach them all that they can do is escalate a problem not resolve the problem. Over and above that both the email addresses for their complaints department don't work and if you are able to reach them telephonically they can only escalate the problem. At NO time are you actually able to communicate with a person who can resolve any issue you may have. Even going into a branch does not help as all that the reps in the branch can do is escalate the problem. Are you being to see the problem??? Once my current contracts have ended MTN will receive no further business from me as I need a "Service Provider" that offers service.
