I get wanting to rant a bit, but give the shop and Trek a chance to resolve the issue.
I agree it sucks, but Trek is known for making great bikes. Sometimes people make mistakes and you even rode the bike 6-7 times before the problem surfaced. So, no reasonable amount of finale QC at Trek or the shop could have caught this. Though no question someone screwed up somewhere. Could be something out of Trek's control. For example, like some sort of defect in the bearings. I doubt Trek makes their own bearings.
You just have some weird problem that you should have no trouble resolving with your bike shop or if needed a warranty claim with Trek.
I'm sure it will all get sorted pretty quickly.
Best of luck and I hope you are on the road soon.
