I believe it is only the Enterprise accounts that have a "concierge" service.
I'm an anchor store and "all" I have access to in the current environment is seemingly vastly improved customer service reps, as opposed to lower store levels.
Otherwise if I have one, my "concierge" is ignoring me...... years ago we (Anchors) did have account managers they called me up a few times but that was a long time ago, probably 10 years......and even then they didn't really have anything to add to what I was doing, I'd been here for over 10 years by that time, often I had as much knowledge of how things worked as them if not more sometimes, especially with respect to my own "domain" (stamps).
