This is a scam calling. They left me a message stating it was the IRS and that they were suing me and putting out an arrest warrant. But that I should call to avoid it. Call back and it's just dead air.
Got a call and voice mail. Caller was a female robotic voice trying to sound like a human. "Hey this is Officer Catherine Richardson FBI badge number 002570, calling about a tax issue..." Huge scam, as the FBI will not have a robot call and they do not leave messages like this. HUGE SCAM... Block them and report to FTC.
