Furious client

My car was bumped on the 4th of July and kingprice did their investigation and found out that I was not at fault. Kingprice phoned me and told me that they are going to fix the car and I should prepare to pay the access of 6500 of which they told me I will receive it back after claiming from the third party. Its almost 5 months now and I haven't received my car, I was told the supplier still waiting on back order. How do you take 5 months to fix or wait for a back order? Kingprice is just taking me for a ride.
