On April 14, 2017, I received a call at 1:22 PM with the Caller ID showing: "301-429-9642 Maryland". I don't know anyone with that number so I picked up and heard nothing but silence on the line. I answered with: "If you are a telemarketer, I am a pissed off Klingon!" More silence so I added: "And I am sharpening my b'athleth to use on YOU!" They hung up without saying a word!
