We reveiced this call via a Voicemail today. They left a message saying they were the "Legal Affairs of the Department of U.S. Treasury, the Internal Revenue Service." Stated that we had a fraud on our taxes and needed to call them back. We knew right away it was a scam. I called anyway to get more info. I introduced myself as an investigator. The man on the other end had either an Indian or a Pakistani accent. He kept pretending to be with the IRS, and asked me to meet him at the IRS building, and gave me a badge number, then hung up.
