A guy said he was from the IRS and I underpaid on taxes and they had issued an arrest warrant for me. He never once said my name or anything when I answered to see if he was even talking to the correct person. He started right in with his speech and only called me ma'am. He was extremely hard to understand with his accent. I told him the IRS never contacted me via mail and if I do indeed owe then I should have received something. He then told me if I hung up the arrest warrant would go into effect. I laughed and told him good then hung up.

Tried to reverse prank call them and no answer

yeah, I got the same phone call from this silly guy and spoke same [***] to me before, he was a fake head with no sense, I hope he really get arrest by someone and someday.  He has to practice more of his oral saying in English without his heavy accent of Indian something, I don't believe IRS is hiring someone who can not speaking in fluent English. Please don't be make any call to scare people and said to arrest the people with no sense.
