If you don't want to mess with the guitar which I can understand then the first thing I'd to is contact the company you bought it from. They may have someone in your area who can fix it at no cost. Maybe they'd reimburse you if you have to take it to a non-authorized dealer. Neither you nor them want you to have to send it back. I'm going to say that for someone with experience this will be an easy fix.

ETA: When you say "loose" do you mean mechanically loose (things rattle) or electronically loose (the sound cuts out)?
