Replying to Roof box flew off on the highway

anyone have this happen to them? absolutely boned yesterdays vibes, box has a bunch of holes in it and the roof bars are all mangled up. my skis are mostly ok got a few scrapes and shit. I have no clue what to do everything was installed properly but im guessing that yakima wont be all that willing to dish out the money. honestly just glad no one got hurt, it was dumb scary looking up out the roof and seeing my ski box 10 feet above the car
