Same here I kept getting calls from 202-738-4367, numerous times!! I blocked it yet somehow the call kept coming through. Today it was an animated sort of message, that was captured on the end of the message, saying it was about a case file, it was urgent that I contact them at the number given above. I called them, was answered by a someone that I could not understand, however he has called ID and knew my name, scary!!. I had trouble understanding him but he said IRS has a case open for me and it was important that I meet them at the court house, huh??? I asked why had I know received anything in the mail as I knew that would be the way that IRS would contact me and not a phone call. Told him I would call IRS directly on their toll free number. I knew I had done nothing wrong and hung up on him.
