Audible Illusions M3B question

I month ago I decided to trade in my older AI Modulus 2 for a new M3B, sending in my money for a trade-in and have heard nothing since. My emails have gone without response, and phone calls to Jerry (described as service manager) are not answered and with no voice message ability--just rings. Needless to say, I am becoming worried that I've been scammed by these folks. Has anyone encountered similar issues? Any suggestions?
