Well, now it seems my number is on their afternoon schedule--they called a week ago at the exact same time as today. About 10 calls since last November. My call blocker doesn't like "Unknown Name" so these cretins can just hold their breath waiting for someone to pick up such a robocall.
Number has called several times. I decided to answer to see what it was. Answered, hello, no response, Click. Stayed for 20 additional seconds, click! Then a recorded voice: "if you would like to make a call. . . . ."
