Got a call from someone claiming to be an Agent Frank Llewinsky from the FDA. They were looking for the former owner of my cell phone number, not me. I called back and left a message that they had a wrong number if trying to reach that person (did not leave my name, but probably wouldn't have bothered returning the call if I had read this info first). If they call again I'll file a complaint with the police or FBI, whichever makes the most sense. I'm pretty sure "Impersonating a Federal Agent" is a federal level criminal offense, and that the FBI would want to be shutting down scammers like this.
