wOw, I am so sorry your having to go through this crap into 2013
How far are you from Arlington / Mansfield area?
there is a fellow BMW / Porsche owner who owns his own bodyshop and there top notch
let me know is it's near enough for you to give them a call.
I would definitely document everything that you've went and will go through with these guys and prepare yourself for court.
sounds like they need a good kick in the "Go-Nads" for treating you this way!
try the advise of "DallasBoosted" it seems like the only play to get them to do right before someone looses there job.
good luck cymk
