UPDATE:
so i got management involved and they sent out all their plow trucks to see if any of them lined up with the dents. we found the truck, but some of the drivers (morons) actually tried to get out of it by saying that, even though 2 separate dents lined up perfectly with the 2 dents on the car, "the truck was full of salt and would have sat lower than it does right now." Don't insult my intelligence! BTW the truck was red, the paint in the scratches is red. i don't claim to be Sherlock Holmes, but this is just ridiculously obvious!
I don't have collision coverage, which means that it's not covered. and as it is, there are no real witnesses. this is gonna be a bloody battle...
i mean i'm not out to get rich. I just want my car to look like it did. this is gonna SUCK!!!
