Complaint Review: Patrick Rosenthal

I backed an indigogo campain for emospark in October 2014. it was supposed to be delivered by Christmas. It is now almost September and a year later and still never got the order. on their web site there is a forum with pages of complaints about this. The problem is they will not to respond to emails or phone calls. I have tired to contact them many times and get no answer what so ever. I don't know what to do next, it looks like I paid $350 for nothing at all.
