Replying to Mounting Mess-Up

Hey, so I got my skis back today and after looking at them, the shop has kind of fucked up both heel pieces.  I have the scratch 120 bindings and the problem is that they did a really sloppy job screwing down the back screws.  The binding is not even flush with the ski and there is about 3.5mm of space on the right heel piece, and about 1.5mm on the left ski.  I can definitely see through both heel pieces, even though it's just a sliver of light.  WTF do I do about this?  Will it be an easy fix or will the whole thing need to be remounted? 

Am I entitled to some form of credit from the shop?
