Had screen replaced and now laptop creaks, feels loose, etc.

Today I picked up my Macbook after having the screen replaced. AppleCare paid for the repair. I didn't take my laptop to an Apple store because I generally find them to be unhelpful and rude, but instead took it to a small authorized repair store. Immediately after picking up my Macbook, I noticed that the hinge was not attached correctly, as the ends of the flat rectangular part of it were popped out. The tech took it back and said he would have to take it apart to fix the problem, but called me five minutes later saying he popped them into place. That worried me.

I took it home and began using it and noticed that the hinge feels very loose and creaks when I open it. I also noticed that the casing around the screen does not actually connect with the screen on most of the right side. There is a noticable gap that I can press down so that the casing touches the screen. The laptop also makes a popping noise when I type or even just move the laptop while it is sitting on my lap.

It seems like my laptop was hastily reassembled after the screen was replaced and I'm very disappointed. My Macbook was in very good condition when I left it. To make things worse, I live in Kansas but go to school in New York and am flying back to school tomorrow, so it is impossible to take the laptop back to the same repair store.

Should I call the repair store and notify them of these problems? Should I call AppleCare? Are any of these problems likely to cause permanent damage to my laptop or can they be lived with?

Oh, and, in case you were wondering, the screen itself is impeccable. Irony.
