My wife received a recorded call on her cell phone saying the IRS was filing a case against her and to call back. I called back on the home phone & a recorded message asked for a name, then to leave a message--I left 'em one all right!!
Update: I accidentally misdialed--A thick foreign accent answers this number, and is not very understandable, but it sounds like "IRS". When he asked for a phone number, I gave him a fake one & he replied,"Do you want my name? ABCDEFGH....." This is the 3rd scam cal in a week--2 on different cell phones!
