A person (with last name of either Hoffman or Kauffman) claiming to be work for the IRS Criminal Investigation Division left a message on my answering machine informing me that there has been a notice issued against my name and for me to urgently return his call by contacting this "hotline" number - (202) 241-1272.
I have not called or intend to call this number. However, I will call TIGTA (Treasury Inspector General for Taxpayer Administration) @ 800-366-4484 to report the unsolicited call. I will also file a complaint with the Federal Trade Commission thru their website: www.FTC.gov
