Who called from 5593964481

After I say Hello, a recording says "I'm sorry that is not a valid extension, please try again."  and then disconnects.

Received a voice mail on cell phone at noon today-6/24.  Accented male voice informed me that I was the subject of a grand jury investigation and I was in trouble.  Advised me to immediately call back.  I consider this a threat and a crime.  What is our govt. doing about these calls?

Middle Eastern accent recording from the, "government", telling you this is your 2nd, "warning", to call them or face being tried in a criminal federal court. Nothing but bogus, POS, who would be in Guantanamo Bay if I had my way.

About my credit card and need to push 1 to talk to someone. it came in on my cell phone I just put it on my blocked list.

I got the same message from male with accent--said his name was Daniel Rogers, US Treasury, and I had committed a criminal offense, etc.  Also got the same message from 619-924-0148.
