Replying to Remount question

so i have a question. after lookin thru other threads ive found that skis normally dont have a prob being remounted and sometimes can use the same holes. however my situation is different from most others. as a good kid, i got my boots a size or so bigger so that id grow into them, but im short and decided not to grow and prolly wont. the stupid store that mounted my bindings mounted the heel piece all the way forward on the plate so i cant move it forward w/o a remount, and i ride invaders so that means remounting both toe and heel piece. normally it would be fine cause the previous holes would be underneath the binding, but with my remount they would be infront and behind the binding and with one hard landing im sure its not gonna hold since the invaders are as thick as a piece of paper.

my questions are: am i correct in that they prolly wont hold up the whole season and with a hard landin on the tails break? should i go back to the store and tell them that they fucked up and get me new skis(they are less than a year old) since i already had to have the 06 invaders replaced with their whole delam prob and now its another pair thats gone bad? i work at a sports store and one of the guys suggested that they should have been mounted atleast a little bit back from the front of the plate and that i could prolly say they screwed up and they gotta fix it?

any suggestions
