insurance seems to say ive been driving a 3 wheeler

Two months ago I had to drive myself out of a hi jack situation. The guys had put rocks in the road in order for me to stop. It was either my life or my car. My car was obviously very badly damaged and looked like nit was beyond repair. My car then took two months to get fixed by insurance. I car had a few small scratches on due to the rocks splattering id assume on the covers of the side mirrors. The front driver wheels was also damaged and many other damages eg oil leeks and engine damage. My car firstly did go for pre inspection prior to this happening. No damage was found on the car. Currently the insurance is now wanting me to fix my own wheel and the little damage done to the body. I've called and tried but got feedback saying that this was not due to the accident. Yet the wheel is so damaged that the pump doesn't even last a few seconds. It deflates immediately. I've called budget who said they will get back to me but they instead emailed the repair shop to inform me that they will not do any further work. Id now have toe my car as the wheel is that bad and unsafe to drive with. Please help as I'm now not sure what to do. I have an access of 10k already that I had to pay today but how when I don't even have a fixed car.
