RaceWash Car Wash on College Road review: Damage to my vehicle

The Car Wash damaged my factory installed Spare Tire Cover to my 2007 Toyota FJ Cruiser. It came off during the wash and the Car Wash refuses to replace it, they are saying it was already damaged, I have pictures of it showing it was not damaged. They claim it came off because of their strong blower, which is actually right, but they don't accept it's their fault for not warning that this could happen. They should at least pay for a replacement cover which is $169.90.
