Replying to Mounting, Arggg.

So i just got a pair of griffons mounted on my chronics and i specifically called before getting them done and i asked for -2cm from CENTER.  The dumbass owner at the shop mounted them -2 from recommended.  Now the skis are totally thrown off for park. What should i do about this?  i know some of you have definitely had this problem.  do you think they would replace the skis, or just remount them forward (that would be the third mount).

and just to be sure, when i ask for -2cm from center, that means measuring the ski from tip to tail and taking the center and putting the midsole 2cm behind that mark, correct?
