Has it been the same guy you have talked to a few times? They have to have some other form of contact. The end of March is insane of a wait. I would do all I could to get someone on the phone and I would demand my money back. If they refuse i would get who ever I had to involved to get my money back. I hate that your going through it but thank you for sharing it. I wont ever buy from them. Stay on them and good luck.
