MTN Insurance claim

I am still very unhappy with MTN. They sent me an email confirming that I will be contacted by the insurance claims supervisor. There as no callback. I has to send another email to admyntech to query about my insurance claim. They rep**** with a ticket ID that the insurance claim is open. No change has been made and it is really draining waiting for a claim for 2 months now. Agents are giving the same feedback that the claim is with the underwriters or no feedback at all. I need a phone urgently, I cannot access emails or receive important calls under my number. Please assist, MTN has really bad customer service and should they reply, I do not want a private response as I will not be able to open it.
