This scammer is relentless. I defeat the scam by letting my answering service handle all unfamiliar callers. It works 100% of the time. Most callers don't even leave a message. They continue to call again and again until they have a sudden epiphany. After about a week or two, they realize they have better things to do. No answer, no harm.
