King Price Insurance - Don't ever try to claim

I have been waiting now since 11 November 2021 after a smash and grab incident for a side mirror on my car and nonworking electrical window (which was replaced after two weeks) to be fixed. The claim was finally authorised and the car was booked in for 1 December at Keiths Panel Shop - I got there and was informed the spares were on backorder as it was not available. So two months later ... I just phoned again (I am not getting a peep out of my useless insurance company, which was quick to inform me I only have 90 days to get it repaired) and guess what? The spares are still on backorder ... with no ETA ...
