Horrid Service

I submitted a claim for my phone which was ****** on 06/04/2015 and haven't received any feedback whatsoever from MTN insurance, I had to call the call centre and follow the prompts to see if they have received my claim, I spoke to a consultant who put me on hold over 10min until I got cut off and still didn't respond through e-mail to give me progress on my claim, I sent an email complaining and they didn't bother to reply, complained on twitter and still nothing. I've had it with MTN, its been a month now and nothing has been said to me about my phone. I can't be without my phone any longer, can some1 at MTN just get back to me? What's the use of paying for insurance all this time and when there's a claim they are a no show!!!
