Insurance claim with zero follow up!

My phone was ****** on sunday the 20th of March 2016, I sent an email on the 21st march to corporate insurance for some guidance to what I should do as I was an autopage client, I also sent an online insurance claim form on the same day. I noted that they had a turn around response of 5 working days and thought I was getting somewhere when I got a response asking for an alternative number to contact on the 23rd march, but that was the last time I heard from them. I have tried to call the insurance numbers 808 and *** about 15 times since then, all being unsuccessful and waiting for 15 minutes only to be cut off. I eventually faxed and emailed my claim for again on the 29th, still had no response, contacted mtn twitter to help, nothing was done so I drove to Morningside MTN to help, they gave me a ref number #*** on Thursday 7th April and since then I have had no follow up after again i've tired to call the above mentioned number with no answer. As an autopage client previously and being moved to MTN this is the worst first impression I have ever received. With autopage it was dealt with within a week, and here I am three weeks later still waiting. DISAPPOINTING!
