Replying to Line Step up get lost camber - now has rocker!

Hello NS

So last year friend of mine bought some Step up's from Line. Model 10/11 and after like 30 days of use they lost all camber and got slightly rocker. He shipped them to line europe and they gave him 50% off for a new step up 11/12. Now the same happend again. Did this happen to somebody else? My opinion: this shouldn't happen to a ski after that short amount of time. He's an average park shredder who treats them very good!
I have to look on my harddisk perhaps I can find a picture to show.

thx.
