Surprised to see that this number hasn't been reported yet. Text-to-speech female voice (officer Catherine Richardson) says the FBI is investigating my address (never given) and an arrest warrant has been issued in my name (never given). Badge number, case number, tax evasion, blah blah blah. Don't listen, block it. I did.
Same message exactly as "Matilda" reported (received on 5/11/17). Funny thing, I remember receiving the same call/voicemail msg 3-4 months ago. So, it seems the FBI's enforcement division must be pretty lackadaisical since no one has yet to show up with that arrest warrant.
