I'm paying my premium each and every month but yet they can't help me

I'm so disappointed in them, been with them for 3 years and this year I had an accident (26/07/2021) and my car is not drivable so I had to take a courtesy car.. They took my car to the repairer of their choice now the repairer is taking time to fix my car and they say they are still waiting for parts. The problem now is that king price doesn't want to give me or extend the courtesy car hire because waiting for parts it's not their problem but then again it's not my problem and I didn't take that car to that repairer they are the one who chose that repairer and again king price always take time to authorize on the claim..... Now I'm left without a car, I'm working irregular hours and it's so dangerous for me at night or early morning
