Damn sorry to hear that. I'm moving and thought about having my Monte commercially hauled the 500 miles, but wondered what my recourse would be if the car was damaged, so I'm doing it myself now ha.
I'd send a certified letter (be polite) to the company requesting reimbursement for the damages; an estimate from a body shop (or an appraisal from an insurance company) to back up your numbers would help. Keep a copy of the letter and proof that it was delivered. I'd imagine there's some sort of liability/property damage insurance clause, even in the most generic sense, in whatever transportation paperwork you signed. If the company doesn't acknowledge your certified letter, start preparing a small claims case. I'm not a lawyer by any means, and this is definitely not legit legal advice, but it's just what I've done. I took the guy who did a terrible job installing heads and cam while I was deployed to small claims court to get some of my money back after his work destroyed my engine. Laws vary from state to state and maybe even county to county, but you should be able to represent yourself and there is no jury, only a judge, so if you make a common sense case (pictures, contracts, the certified letter that was ignored, get the company to admit under oath they did something wrong), you may win. Collecting on the judgment is a whole 'nother story, but that's the direction I'd go.
Oh, and I'd post up on whatever medium you can (Google reviews, facebook, forums, etc) the company's name and the terrible job they did to warm others.
