My NIB DI was built like a tank. I loved that game and played it constantly. When the phone part died (such a cheap product...) they ignored my emails and phone calls repeatedly. I forgot how I finally got someone to help me. It was about 8 months in. To their credit, they charged me for the phone and gave me a refund upon receiving my dead one.
I never forgot the lack of support though, and that's what made me stop buying from them and start buying from Spooky. Customer service is so important these days.
I was on the fence with GnR. If that was a Stern or Spooky game, I would have purchased it day one. JJP made me hesitate, and then when they raised their prices mid-sale, that was an obvious "no" from me.
Sorry to hear about your troubles. I hope it all works out.
