Answered phone while watching video.  I gave the standard greeting while pausing video, and it was a robocall.  All I could catch was "... changes to your bill. If you are the person responsible for the bill, press '1'. If not, press '2'."  I did not press anything, as I had no idea who they were, let alone what might have changed.  They hung up.  Did a web search, and I got nothing.  I called back, and I got "This number has been disconnected..."  Blocked.
