Bodyshop f_ucked me over. Need advice

[hbui_2]

I was havin my bodykit painted at te bodyshop, they messed up the paint 3 times. Took 2 months and it's still not the right color. I paid my friend to put on and off the parts 3 times only to find out the color did not match an had to take back to them. Now the parts are on the car, at the shop and they want to charge me 350 to take the parts off to paint and install. My friends won't do it again since its a pain in the rear. It wasn't my fault that the color did not math. They said it would be ok to paint while the parts are on the car and now they are saying otherwise. I'm very pissed and the owner wants me to pay the 350 or they can't paint afraid the painter will mess up my oem paint job that are too close to the kit... What should I do in this situation?
