This must be one of those cases where they spoof a number. I answered and immediately received a recorded message indicating that I should press "3" if I wanted to receive my benefit and to press "9" if I wanted to opt out of receiving my benefit. There was no company name and no indication what the benefit was. I did not respond and eventually the line went dead. When I pressed redial, I received a "this line has been disconnected" message which leads me to believe the number I saw on my display was spoofed.
