Replying to Skis & Fuct Edges.........warranty's??

I had the old Dynastar Concept skis with the Rasta colours on the bases. After a season the edges were completley ripped out of the side wall, the length of my boot on the side i slid rails. This was obiously from sliding rails. Dynastar and shitty edges what's the go?

I have some PE's from 2 seasons ago, i slid rails on them for around a month in total, then last season with hardly any rails. The edge on one ski has started to lift away from the side wall. I call up the store where i bought them asking about it, basicly their like "ohh u slid rails, bad luck."

This pisses me off because u buy these skis for the park and or all mountain and obviously rails are involved with the park. k2 advertises "new thicker edges" but still they tell u to get fucked when u slid rails. No warranty.
Has anyone else has this kinda issue or am i just an unlucky one?
