I find it's hard to form a relationship with my LBS. We only have one in my town. I plan to visit two other LBS within a half hour before I buy my own bike. I want to make sure they are someone I can form that relationship with first. I understand your pain. I do think it's okay for you to report back their adjustments aren't working. I'm sure they will help you with this and are probably more used to it happening than you realize.
