I NEVER EVER answer my phone to unrecognized numbers.  Lately I'm getting calls that caller id says is coming from Cape Coral.  Whoever it is, doesn't leave a message.  My research tells me that this is another bogus "survey" call.  Too bad we can't show up at their office and without saying a word, just walk up to the first scumbag you see on the phone and slap them as hard as you can across the face.  On your way out the door tell them, "I was just taking a survey on how many telemarketers like getting slapped in the face.  If you wish to no longer take part in my survey, press what ever number".
