no feddback and ignoring emails and calls

I have been dealing with Mr Jay Govender, CIP Administrator, regarding my husbands account. He has been ignoring my phone calls as well not responding to my emails but when he does, he only answers what he wants to answer. If he cant answer my questions then get somebody that can answer me. This has been going on for some time and the service is pathetic. Why cant it be sorted out then and there???? It is not rocket science. Just answer my questions. And im still waiting on MTN to contact me with the previous hello peter complaint. Email me as I will not answer my phone.
