This number showed up in Caller ID. They did not leave a message, making them "suspect." We call-screen. No recognize caller, no pick up phone. Put them on call-blockade. Message to them: "Up yours."
Got the call, answered... no response, but long delay which is indicative of an auto-caller switching over to a live person. Hung up at that point. Blocked #.
Also got a call from this #-did not pick up. Called the # back in 15 minutes and got the standard phone company recording of "You have reached a number that is no longer in service...." confirming that the robo-caller's Master was definitely NOT someone I wanted to speak to. Just another sham artist I didn't have to say NO to but who would then put my # on their "live person answered" list and then Still make money by selling the list to their scammer buddies so They Can Call Me Too. And Yes, I disabled my own CID when I returned the call......
