Called but left no message so it can't be important.

Called me to but no message

Robo Call left a message pretending to be a human to get you to answer.  No further message left when it didn't get a response

This number has called my Cel 4 times I'm less than a week. After the first one I added it to my blocked list with the call blocking app I have. When I don't recognize the number and there is no name with it I never answer. If I do its to immediately  end the call.  Then immediately add it to my blocked lists. Ever notice how sometimes they try to call right back?
