Replying to Shop mounted bindings wrong

Old thread is dead and, well, old.

A little background: Got a pair of 2020 Faction Prodigy’s for Christmas from Evo. Supposedly came with bindings that weren’t mounted. Long story short they came mounted and at Factions center line. Went through a bunch of BS and basically returned them to get the 2021’s without bindings. Brought those to the shop and specifically told them to mount true center. Whelp they mounted them at the manufacturer center line again (6cm’s back from true center). I’ve been a park skier most of my life, always mounted true center. I also like to ski switch quite a lot. Since suffering a head injury I know I won’t be skiing park much anymore but still love to ski switch. I’m on the EC so powder isn’t going to be a massive factor. But I’m still annoyed, I’m not really a fan of the bindings this far back but since I really haven’t skied that way before I’m not sure if I should make a big deal with the shop about it. Plus with Covid I know these shops have been hit hard and don’t want to take more money out of their pocket. I think 2-3cm’s back from center would be more my style. I guess I’m just looking for some input on whether it’s worth pursuing before the skis get used or if I should try them out. Any thoughts would be greatly appreciated!
