Received call from 202-241-9754. Computer voice recording stated they were with the IRS and it was a time sensative and need to contact immediately before they take further action. They concluded with "take care".
Couldn't hear the whole message, most of these automated messages don't wait for the outgoing message to complete, but it ended with the phone number to call back and an admonition not to ignore the call or else "action will be taken."
I just got a call from this number and said the IRS has a warrant for my arrest for cheating on my taxes. Ha! IRS does not call people like that. If they call back I might answer and have my police scanner going loud in the background!
