This are IRS impersonators. They have thick Indian accents and give themselves the most American-sounding name possible (Steve or Jack), and then. The asked for my first and last name when I called them back and I gave them a fake name. They sad that they were calling because of unpaid taxes, and I need to wire money to them right away to avoid being arrested. Complete scam. I already reported them to the IRS website. Can't get them to stop calling my number though!
