MTN INSURANCE at its worst

I lost my phone on the 12 September 2015 and thereafter went to lodge a claim at Menlyn Park Mall MTN.It has been a week now that I have been trying to contact MTN Insurance department on ***, *** as well as emailing them with no response.I am up to date with my account so what exactly am I paying for if I must still encounter such inefficiency and unreliability? I am currently phone less and awaiting very important phone calls on that number ***) and I'm starting to think this may take months even.I really think you are being inconsiderate and need to review your customer service. My reference number is ***1 and you can contact me on ***.
