MTN - Very poor customer service

MTN really don't put clients first. After trying for 2 months not to sort out a billing issue. The call centre cannot put me through to billing(THEY DONT SPEAK TO CLIENTS), all they do is play post office and escalate to billing by means of logging a ticket(***) which means nothing because the ticket doesn't mean someone is going to call you back with an update or get the problem looked at. I need HELP!!!!
