I'm not sure if I understood that properly, but it sounded like the people that did the second mount fucked up huge? If so, I hope you have a receipt, but I have a feeling they might not do anything. Go to them, talk to the manager, tell them that they made a hugely obvious error, that there is no excuse for, and then ask for some form of compensation. It sounds to me like your skis are pretty raped, which sucks, but talk to the store manager, be polite and don't be angry, just make sure you're reasonable, they won't pay you for your hellbents, but they might compensate for part of the cost of new skis, or for the mount job or something.
Let me know if I got that right haha.
And it had to be asked....
What school did you go to for grade 1-6?
"Firstly Pollard has a fierce rock wall of defense on newschoolers. People are immediately trashed for ever cursing his name. Tanner too has a loyal following, but in his course as the master of mordor, many have come to see fault in his ways.
Only Simon Aragont, with the help of the white wizard Eric Gandard, and potential allies TJ Shimli and Jon Legolosson, could ever defeat his mighty power. But wary they must be, for the C-orcs have been known to lurk around the base of the marijuana volcano!"
