Horrible service from SAU - south african underwiters

I have never experienced such a bad service in my entire life. I logged a claim on the 11 december 2017. I was advised to go collect my car at my own expense to avoid further storage charges from the towing company. I towed my car home and I was assured by the claims advisor that the assessor will be appointed asap. The assessor came through after five days. To date and it is now 27 December 2017, no one has bothered to revert and advise what is happening. Every time I consult with the claims department, the answer I receive is that the investigation is still in process. My car is currently sitting at home and nothing has been done to have it repaired. I requested my cover to be terminated effectively. As always the case, I havent received correspondence whatsoever from SAU.
