I had 3 voicemails today from this number saying that this was the last chance for me to contact a federal agent to resolve an issue and that I should please call this number and ask for a federal agent. It was the same robotic voice that I had on 2 calls earlier this year, one from California and one from Oregon. This number is from Silver Springs, Maryland. Everyone knows that the IRS does not call people, but sends a letter if they have an issue with your taxes. They do not harass people over the phone. I live in Illinois and am going to report this to the State's Attorney.
