I just filed a complaint with the Better Business Bureau. Sold my TI-83 Plus calculator to them a few weeks ago and received no check. I tried e-mailing several days ago, no response. Tried calling today, got that same voicemail of some guy. Sent a message to the AIM screen name, no response. I will get my money back or I will show up at his doorstep- the address listed is a RESIDENTIAL HOME. Wish I had seen this site before sending my brand new calculator to this fraud.
