Lack of transparency/dishonesty/responding

Complaining again about MTN. My initial complaint has not been dealt with yet. And it just continues.. What is going on at MTN????? . MTN is NOT A RESPONDING COMPANY ON HELLOPETER (regardless of them being listed as such). How do we get matters resolve? What is the escalation procedure at MTN? I don't want to speak to people without the competence or authority to deal with client matters. Please provide me with details of who I can speak to so I can resolve my MTN issues. Please don't ask me to phone 808 or 173 or speak to a Supervisor. Been there and done that (2-3 times a week since August). I need a person in higher authority's contact details? What is the escalation procedure (short of ICASA)? Desperate, disgusted, disillusioned.
