Got a pre-recorded call allegedly from the I.R.S.  They wanted me to call 415-251-9813 immediately or they would have to start legal proceedings.  I know that the IRS only contacts you by mail.  The caller's syntax sounded like one of the usual scammers trying to get you to reveal ID data.  I did not hear the beginning of the call so I do not know what name they used.  This call came from Novato, CA and was probably from a burner cell phone.

Rec'd same type of call as Derf - I believe the caller was "officer Grey".  Hard to hear the first 3-5 seconds.  I paid my taxes.  I am also under the impression the IRS only contacts by mail.  

Total scam call.  Poorly executed but likely to scare some people.  The IRS would never make a call like this.    

Received the same call...emailed www.tigta.gov (IRS) and put in a complaint.

Total scam. Heather Grey was the person they ask you to contact. I called and let them have it. When I said I want proof they are the IRS he said we are the IRS. I said good when I call the 800 number for the federal IRS then they should have the same story. He said we are federal and the 800 number is the local IRS. I laughed and hung up.
