Replying to Messed up mounting

so i got my arvs mounted last december and i thought everything was ok.  I pulled off my bindings last night so that i could sell my skis this weekend at the ski swap.  one of my skis got drilled wrong.  There are eight holes that have been filled in.  not just like another drill pattern but ramdom holes.  all these holes were under my bindings soi did not notice until now.  i am going to take my skis to the place i mounted them today.  i was wondering do you think i should just ask for a free mount on my new skis or should i ask for more.
