Two possibilites. One is that you're not using the QR correctly. The other is that the hub's bearings need adjusting.
One way you can tell is to jiggle the rim with your hand on the QR unit head and see if you feel movement. If so, the QR needs adjusting. If not it's wothin the hub.
To adjust the QR, stand the bike straight up on the floor, (maybe have someone hold it for you, or leaning in a doorframe) open the QR, and turn the nut on the left side a bit while testing the tension by closing the lever.
QR's vary but typically you should adjust so you begin to feel resistance about half way, then be able to close it all the way with reasonable force. (Remember you want to be able to open it). Be sure to close it all the way flat with the frame. The tightest spot is before it closes flat, then it actually loosens a bit which is what keeps it closed.
If the QR is fine than it's a hub issue and you'll need to go back to the shop for a free adjustment.
IMO- you should go back anyway, because they should show you how to use a QR, and make a number of user adjustments. Part of buying from a shop is the support provided with the sale, and if they didn't give you basic instruction they haven't finished their job.
