My dad taught me to have fun with telemarketers. Answer without talking and hold the phone to the sound of a flushing toilet...or..if they call again. . ..Blowing a whistle as loud and hard as you can into the phone unplugs their ears ..so they can hear that you dont want them calling again. Better than a do not call list which is also an option to implement. ..takes about a month to work. the whistle works very fast.
