This entity continuously calls and hangs up after two rings or as soon as I answer the phone. I returned the call and a message stated it was doing this for a study on current events and that they are sorry if it interrupted us. No way to discontinue from receiving them however. Very rude and obnoxious when I am on the do not call list.
I am having the same problem as Dick Miller. The calls have been coming every few hours and are just identified as Local Call. I answer and there's no one there. I am also on the Do Not Call List.
This number has been calling my home almost daily and never leaves a message. Typically it rings about two or three times then it cuts off. Very annoying and I too, am on the do not call list.
