Same thing here. Called twice in 2 min. Second time they left a message. Robo caller saying there is a tax fraud case against me and I need to call them back or I risk being arrested. If you really had tax fraud or anything like that from the IRS, they wouldn't call you, you'd get a letter and an auditor at your front door.
Received call this number stated he was C.Parker an Officer with IRS and if I didn't call this number back asap I would be arrested for tax fraud caller I.D. Showed this call was Sebel
