I feel left out that I didn't get a robotic message--a couple sec. after my voice mail prompted the caller to leave a message, the a**holes hung up. Serves me right for not answering live! (sarcasm off)
But seriously, folks...
Some previous posters have reminded you not to say "yes" or "no" during any "conversation" with a robocaller. That is a very good reminder as these spammers may lift your "yes" or "no" and use it for something nefarious. Like giving them permission to withdraw your money!
