Just got a call for that same number (from the 412 area code) that was from the Pittsburgh area. I answered but got no reply. Not even a message. No automated junk, either. Just dead silence. The call was placed at 8:47 this morning, central standard time. Called 'em back and it went to an automated voice mail system about credit cards and needing to verify...so got 'em on my do not call list.
