These morons called me again, this time today at 1014 hours. As their number was blocked, the call blocker disconnected the call after the first ring. Unfortunately, they immediately called back, which thwarts the call blocker. So I picked up the receiver slightly and put it right back down again so they wouldn't waste my time.
Caller ID simply shows "Chicago IL". This number has called my office several times. I do not answer callers that I do not recognize. The caller disconnects without leaving a message. This is clearly another criminal fraud/scam caller looking to trick people into providing personal information for purposes of identity theft.
