This is a criminal scam. They call from different numbers (including different area codes). Google cannot find a commercial company with any of the numbers.
They call us daily, sometimes twice. Prior, caller ID read :Insurance SRVC, now it just lists the number. They never leave a message, just hang up on the answering machine. It is very annoying as it has been going on for months daily. I don't want to answer b/c if they hear a human's voice, it could trigger more calls. I need to figure out how to block them.
