Total disappointment

I reported my accident on the 6th of Jan. I had to ask for car hire on the 7th of Jan. I had to call them on the 21st of Jan to ask about how much the longer assessor needs because I need some kind of information. Only to find out that they had received the report and didn't communicate. Then they said they needed documents. Fedex collect documents almost a week ago and now discovery says that the documents haven't been logged in yet. its been almost 7 days since they received the documents. The car hire ends this weekend. How am i supposed to go to work without a car? On top of that I can't buy a new car because I don't know when they will pay me out. I will have to add days to the car hire, which is extra unnecessary expense. The cherry on top of this is that discovery took their premiums for my totaled car.They have communicated poorly and can not see how their tardy actions are affecting me financially. i really do not want to insure with them again.
