Dealership wrecked my car what should I do?

I dropped my 2005 Honda Accord off at the Dealership to fix the "Check Engine" light--found out that the light just needed to be reset.
But then, in the process of fixing the light the Dealership wrecked my car. They gave me a rental car and replaced my bumper.
I did not take pictures of the damages but asked to have pictures sent to my email --just wanted the bumper repaired because according to the Dealership that was the only damage. (Dealership gave me $60 off my $250 bill) :(
But now… 2 weeks later I notice that near the bottom on my door are 3 outward dings like they had to push out a dent; also, the rubber piece that goes along the door, above the "dings", was painted black with a small "paint brush" trying to cover the white paint that was also on my bumper when it was hit.
What should be my next step and what should I request as compensation? Should I start with asking for the paper work and pictures sent to the insurance co and the collision company? What about compensation?
