Delayed service delivery

It's been over a month now that I have submitted my claim for a burglary. I was compensated for some of the items only. When I called the call centre, I spoke to different people at different times and all I got are empty promises. They promised to call me back and some even put me on hold to speak to the consultant who was handling my claim, promised that the remaining items have been authorised and payment would be done but no payment has come through yet. I've sent the claims handler Lethabo many emails even one stating that I'm not happy with her service and still no reply. Further to the above I was advised that I need to provide proof of ownership of an item, I do not have the receipt and now I am left without compensation for this item. I am absolutely irritated by the bad service of the consultant as I feel if she worked properly on my claim then all this would have been resolved by now.
