Got a voice mail to call this number (301)876-4309. They said they were from the IRS and to call back immediately. It was very important. IRS does not call you on the phone. You receive a certified letter in the mail. This is a SCAM.
They just called my son from this number and threatened to arrest him. Why does our fine government NOT investigate these folks and shut them down. Heavy, Middle-Eastern accent, threatening to send police to his workplace. My mother got a similar call and it scared her into a frenzy. She's 85.
