isn't that just gonna push the screw out and destroy the screw hole?
you wanna complain for sure. that will affect the way it's gonna ski.
i've seen it happen to someone who mounted there own bindings and he took the screw out and ground his base down. then he used (this is where i forget the name of that thing you can place into a ski to strengthen a drilled hole, kinda like the line mounting system) before he put the bindings back on.
either way they've probably damaged your ski a bit so they should sort it, either new skis or some sort of fix and money off.
