I am the do not call list and I am having a number of calls from numbers that I am unfamiliar with so I will not answer any calls. Why do they not leave voice mail ?

The call is from Nielsen.  Besides being on the useless "Do Not Call" list, my number is also unlisted and unpublished.  They are relentless, as they call here about three times a day.  Their last call was this evening at 8:45.  They received an ear-full from me.  Hopefully they won't call back, as I am not interested in answering any questions about anything.

From Nielsen Media. They're following up to see if I received my Nielsen Radio survey, and reminded me to complete it. They also provided instructions for when and how to document what I listen to on the radio.

I actually got mail from these people with a dollar bill in it.  I took the dollar and answered a very short survey about radio listening.  Sent it back.  They then sent me $10 cash.  I answered another survey, I think... sent it back... they then sent me 3 more surveys about radio listening with $2 cash in each survey.  So, I've gotten $17 cash from these people for not doing a whole lot of work.  When I send these 3 surveys back, they promise to send another $10 PER survey... so $30 more I should be getting from them.  I'll keep taking their surveys if they keep sending me $$$ =)

Call daily, sent me a dollar.  says they are Nielsen. I tried to do the online survey but when I plugged in my fake phone number they knew it was a fake.  This tells me someone, maybe my cable provider, sold my info.  Told them I don't listen to the radio, we don't have a local radio station.  She pushed on and when asked if I was 15 or older I said no and hung up.  Blocked that number.  So annoying.
