uh, contractor relations are only thereto remind you of what your contract says. They are not there for thecontractor, It should be renamed FedEx relations. These people arefull of hot air and are generally a waste of time and effort unlessyou have a really rogue manager blatantly violating your contractwhich may cause other contractors to complain and lead to some sortof terminal disturbance.
My method was to always solve an issue with the immediate manager, If I can't, I go to his boss, If that didn't work maybe the TM, I never went over a TM's head because that could make my life miserable with the paybacks. Also CS is a waste of my time. I know their deal.
