I also received this call. An East Indian man answers the phone as if he's from someone's office. He'll tell you that they sent a letter to you in the mail about the IRS incident and will not let you get off the phone until you talk to 3 other people. total scam
Same robo message from this number that I got earlier in the week from another number. Didn't say anything but that I needed to call back. SAME ROBO MESSAGE FROM DIFFERENT NUMBERS.
03/19/2016 11:26am San Siego, CA: 1-619-924-0073....Message says....this is your last call, IRS is suing you and need you to respond immediately to this number.. I know this is a scam; but I hate receiving these annoying calls.
