Towing after collision

Wife involved in wreck 6/18/2018 when someone turned in front of her resulting in heavy front end damage, none to rear. Took 10 weeks to get car back. When I got it back I found heavy scratch marks on trunk lid from tow driver dragging magnetic brake light bar off lid resulting in $308 in damage. ASAP would not accept responsibility so I am out the money! I have photos of the damage. It was not there when they towed. Owner said stuff flies over car when collisions occur. Nothing here did! I have dashcam video as proof. I should look into small claims court! Caveat Emptor! They will shaft you if they can! Photograph every part of your car before they tow so they can't worm their way out of their responsibility!
