More destruction than good

I had an accident in May 2021 and my car was delivered to them. The service was excellent but a month after I had received my car I found that things had been removed and not returned but what irritates me the most is the lack of reply from the sales lady I was dealing with. Firstly my privacy screen in the boot had *****s that were removed my guess is that they were put on another customer's car now mine is completely ruined and I now need to buy a new one secondly the private boot had been removed and the *****s not returned thus rendering the boot useless as anyone can open it I raised it with them and to this day I always get excuses that she is not in or at lunch
