At MTN we dont care !

This business is any customers worst nightmare !! The MTN stores where you are able to deal with a physical person are not able to sort out account queries as they are franchise stores. If you phone the customer service number (135) you need to have the patience of a saint - I have been left holding on for well over ten minutes without a response. I am trying to simply sort out why my account is not showing a positive balance but this is impossible. Emails to the customercare address have the same response - nothing !!!!!!!!!!!!!
