They say they're calling from the courthouse and to call back. They keep calling 4 times already today. Because it's coming from the New York area I will never call that back.
Was definitely a scam, robo-call... left message saying it was from "Tax Penalty Dep't of IRS", threatening action unless that number was called back. I filed complaint with FCC and TIGA (IRS) about the impersonation.
This is a scam. Caller identified himself as an officer from the IRS looking to talk to me about tax evation and fraud committed by me. I told him to send me a letter which he claimed they had done. When I told them that I did not owed any money to the IRS and that was very sure of that. He started getting rude and very aggressive, and threatening to prosecute me for non-payment.
