Replying to Mounting issue

So I just got my new skis mounted. I get them home and I'm checking them out and notice that one of the back screws on one of the heel pieces is not screwed down all the way. You can actually see space between the binding and the ski and see the screw. It's not huge, but definitely noticeable. The back end of the heel piece is not flush with the ski. Did the guy just not screw it down all the way? Please tell me they will just need to drill it in further.... I really hope this does not require a remount.
