Better your chances by turning your machine off. As long as they get some kind of an answer, they're going to keep on calling. Try blocking the number, possibly getting a call blocker, or just ignoring the call entirely.
Just got a call on my cell....didn't answer, they didn't leave a message. I cannot block anymore numbers, so now I save the number(s) in my contacts and list the name as "Solicator" or "DO NOT ANSWER"....LOL!!!
