Quality of staff is atrocious.

l have been an MTN custonmer for +- 20 years, recently l had cause to call the call centre to have an issue on one of our accounts resolved, l have never encountered such incompetence from staff who MTN employs. One is given the run around from one department to the next because no-one can explain the charges/amounts reflected on an account THEY have calculated, in an accounting/billing system that belongs to THEM!! I am at a loss, my only recourse is to vote with my feet to another service provider with all 5 contract we have with MTN. If there was a rating below 1 l would have given it to them!!
