It's bad enough that you had to find the damage and that they wouldn't fess up to it. You need to bring the car back in soon as possible and talk to the shop manager, if this doesn't work talk to the dealership manager. I f still no sucess, look in your owner's manual, they have phone #'s for problems like these if the dealership isn't willing to deal with you. If i were you don't settle for having you car repaired, it won't be the same, i would most likely ask them to replace my car. If you push and push and talk to the right people, you'll get results, don't let them push you around, but don't be an ahole either. I would tell them no matter how much they atempt to renbend the metal it'll never be to factory spects, plus you'll know all the time what lies under you car twisted metal here and there. I f you push this issue far enough you could mabey get a car like yours used for free,you never know, they'll do anything somtimes to shut you up, so you'll come back and buy another car. Good luck.
