I received the same automated message claiming to be IRS. I returned the call and I asked the agent "you work for the IRS" he repeated his title and I said that's funny because I work for the IRS too, he disconnected the call. I've tried to call back but no one answerers . I have also reported it to Treasury Inspector General for Tax Administration.
Got a call from 360-342-2032 saying that IRS has files a law suit against me. So I called back and got answered by a
guy with Indian accent. And he disconnected when I asked him what the law suit is about?
