I received exactly the same call. Maybe a law suit against the caller would be appropriate! My phone is listed on National do not call list! 3 calls from them today!
We received 3 unanswered calls yesterday (March 24, 2017). A female automated voice message said "The IRS is filing lawsuits against you. Please call our department number 248-801-9321. Thank you." All three message were the same, about 34-35 seconds long.
