Replying to K2 Customer Service

So after trying to contact K2 through reps, emails, phone calls, I have been left un answered for about 3 months now. Back about 5 months ago I was given a prodeal card from my work for a pair of K2 skis. The prodeal password has coming up as invalid and after trying to reach them not even getting an answer back after 3 emails is getting kind of old. Has anyone else had to deal with something similar or knows of any other ways to try and contact K2? Would be appreciated. Reps names are Kirk, and Dan.
