I will post 2 facts I know since I used to do towing, and recovery!

1. Never accept the car with damage, no matter what they say!

2. When you seen the car the cops should have been called, and when they showed you ask for a report to be filed.

Will it get fixed now, NO... You accepted the car, and probably signed the release which has in small print "we are not responsible for damages, or lost/stolen items"
