King Price taking too long to assist with claim

My husband had a small accident with our car in December., with what seemed to be minor damages. We reported it the following day to King Price. They send out a pick up truck to collect the car. The car was send away for an assessment. I was promised that I would get my car back on 1 February, latest. To date, I still do not have my car back. Apparently they picked up afterwards that my engine seized. They are now suspecting that the engine seized due to an accident that was caused by the dealership where I bought the vehicle, during a car service. This happened in May 2018, and the dealership did fix the car for me. I never submitted a claim to King Price for this. Now while they are running around like headless chickens trying to figure out how the engine seized, I asked if they could assist me with a courtesy vehicle in the meantime. To date no response to this request. Nobody is advising me of the best way forward.
