I'd posit that the Alembic HQ is a small family business, with certainly less than 2 dozen people there on a given day; plus they're dodging COVID and the fires in Northern California, so their attendance is kinda spotty right now.
I'd also say that IF you're ever going to learn to adjust your bass, Alembics are some of the easiest, with the adjustable nut, a one piece bridge already cast to follow the fingerboard radius, and adjusting the pickups is even easier than most. I taught myself to understand and maintain my own axes, as most of us do.
Essentially, you get your neck relief right, then adjust your bridge for the string heights over the last fret, then adjust your pickup heights to suit. I'm as ham-fisted as they come, yet even I figured out how to do it. I'm no tech, and my post covers good-shape axes that don't need real fretwork or other professional jobs, and Alembics also tend to not need one often with the stronger full-length laminated neck, and the 1/4" ebony fingerboard is a great extra-strength stiffener to that neck. But all basses vary, wood moves over time, and if you think it could be better, that's your call.
If it's something you'd rather 'outsource', find someone QUALIFIED, and if Mica suggests Chicago Fretworks, you can take that to the bank.
All the Best,
