Received two calls from this number on July 23rd, one minute apart.
Answered the second time, but there was just dead air on the other end of the line... robo-callers!

Our infamous "Air Duct Cleaning" crew is at it again it seems.  Had a few month break from these after the news ran a big story on this crew.  Based in Karachi Pakistan.

No one answering (late afternoon) when I said hello...just dead air with exception of a bit of unidentified low noise in the background.  Another crank call from the U.S. - Idaho somewhere?  I hung up after two 'hello's without responsive intelligent interaction from a humanoid...I don't have time for someone's stupid games!
