Well my Zex box stopped working. I noticed it didn't turn on. So I emailed ZEX, and told them what was wrong that I had for a little over a year. 2 or 3 days later they emailed back with a number to call. I called and I talked to 5 reps until finally the person they transferred had a voica machine answer. SO i left a message. Waiting for a call back I didn't email ZEX for about a week!! I finally emailed Zex and told them what happen. No reply for about a week. I emailed them 3 days ago saying that I want this fixed whether I pay out of my pocket or not. And still no reply!!!! What should I do?? I dont want to boy a whole new Nitrous kit!
