MTN Does it Again - No Feedback as usual

I had my cellphone ****** and put thru a claim with insurance on the 01/02/2016. I have had no response from the MTN Insurance Department. Despite all my effort in calling, sending emails and faxing, nothing has been done thus far. They are just not in reach.<br> <br> So I say, MTN does it again as I have had several problems with MTN in the last 6 months. Ranging from Insurance to over billing on my account. <br> <br> Does anyone work at \this\" Insurance call centre of yours? Doesn't seem so, even though I have phoned several times, wrote the emails, gotten reference numbers nothing has happened in this past 8 days...????<br> <br> So I ask: \"Does anyone work there\".<br> <br> What should I be doing to get a hold of them. Who else should I involve? I am clueless as to what to do next because despite my efforts MTN does not seem to care."
