Mtn Not Responding Properly To Previous Complaint

Previous complaint *** Refer mike REQ:*** at Mtn. I keep on speaking to Zodwa, at Mtn. Who promised to send me email by 1200 middag, the latest. Which I demanded from her. I feel that it's unnecessary for me to keep on querying, and placing complaints with Hello Peter. Can't someone who is accountable, or can make a decision...Phone me back, as it's common decency. Or do something positive. Mtn has my handset, for a month at least, and I am struggling. Please guys come to the party, and serve me as a customer. Do I really have to approach the Consumer Council for assistance, on this matter?
