Heavy foreign accent claiming to be the IRS. Called on Sat morning, leading me to believe it was definitely not the IRS. They stated they were filing a suit against me and could they have my name? I said " no you may not have my name! However, I will be calling the IRS and turning your [***] in on Monday morning!" They said " I dont care if you believe me or not, if you hang up, the cops will be at your house in 45 min." I hung up...lol
Please do not let them fool you. IRS typically will notify all business by mail.
