The protoplasm may be 72, but the spirit is 32!
Once you’ve identified the call as coming from a telemarketer make a note of their phone number on your caller ID...then sit down and start calling that number. As soon as it’s answered hang up. Keep doing that until the telemarketer realizes that you’re never going to answer. It may take 10 or 15 minutes for them to realize what you’re doing, but once they do they’ll stop calling. IMHO it’s a great way to deal with the telemarketer’s unwelcome calls...it has certainly worked for me!!!
