Just don't understand how they get away with calling.

I just received a call from this number. I didn't recognize the number so I let the call go to vmail. The caller did not leave a message.

call is being recorded.  Press 1-5 to answer questions.  I never press any # or say YES when asked if I can hear them.

Don't know why I answered but I did...Appeared to be a Recorded Political Survey asking for an opinion on the President's performance, only listened long enough for 1 question and hung up.

president performance survey.  They've called 5 nights in a row now.  Hung up first few times, yelled into the phone a couple times, and last call I hit 2.  Not because that's my answer, but just to see what would come next.   It disconnected so guess I gave the wrong answer!  I would love for someone to tell me how to trace these, and all of these tele-scumbag calls to origin.   Do Not Call list is a joke.
