what kind of frame material, what kind of seat post material? Do you have one of those quick release flip levers to secure the seat tube or do you have a nut and bolt?
I'd say torque the seat post (and by that I mean with a torque wrench, not crank on it as hard as you can) and consider using carbon assembly paste to provide some friction in there.
Your best bet is to visit the shop that gave you the tune up and ask them to deal wit it. It should only take them a few seconds.
