3rd party claim nit paying out after 5 months!

I have never experienced such bad service delivery from a Insurance company. Hollard and OVK insurance are responsible for my 3rd party claim. One of their clients dumped into my car and damaged my boot and dented my car. It has been 5 months and they still haven’t paid out my 3rd party claim. Every time I follow up on the claim, they say that they are still waiting for documentation. I have send the documents 4 times already. The inconvenience that was caused to me with my boot that can’t lock is frustrating. I can’t do shopping because my car can’t lock properly. This kind of client service is why we lost respect and confidence in the insurance industry. I’m terribly disappointed and frustrated. I request that my claim is paid out asap.
