Iwyze old mutual and their poor customer service

I was in the accident on the 12 August this year, my car is insured with Iwyze old mutual, I have never seen a company that doesn't care like this one, they took my car in August, still today they haven't validate my claim, it's always story after story when I contact them,they don't contact me, Im the one who always contact them. I have given them everything they wanted but still, I haven't been updated about my claim, I'm really Fed up with Iwyze, I don't know how many emails I have sent to the lady responsible for my claim (Hlengiwe) , but still no response from them. I don't know what to do now.
