mtn insurance does not pay out claims anymore!

For the past 3 yrs I have been consistent at paying my monthly premiums. I have only claimed once before and had no issues. <br> <br> On Sept 23, 2015 I put through a claim (#***6) for a lost cellphone and even today I have not had any response from mtn. They never debiting my account for premiums, but when it comes to speedily processing claims they slack. <br> <br> At their call centre number there is always not a single consultant to pick up the phone. I had to put a complaint on Hello Peter, and only then they responded. I used the email asking for cancellation forms but no response. I have sent all the required docs but still no response. My claim has not yet been processed.<br> <br> Could you please advise if there is a higher body/forum where I lodge my complaint?
