I called back and the messages said "hello thank you or calling the donorcare center. We tried to reach you on behalf of he american family association.  we are sorry we missed you and will try you again later"

When I called it back is said "Thank you for calling sweepstakes.com"

Do a google search for your provider together with "selective call rejection".  Or call them to find out.

Has been calling me frequently, most recently today, April 11, 2013.  Leaves no message.  Says it's from Glenn Dale, MD.  I'm blocking them.

i do not like it

I didn't start getting calls from this # till I put my resume online.   Annoying that the call continuously!!

Calls almost everyday while I'm at work, when I call back its always a message stating something about politics

That number calls everyday, but leaves no message!   Tired of it!!!

Sum Beotch's call like ery 5 min. I am goin NUTS ! STOP CALLING ME !!!!!!!!!!!!!!!!!!!!!!! AHHGGGGGGGG !!!!!!

They call me at least 2x a day

Someone called me from this number today; I suspect that the caller is a collection agency trying to contact someone who had this phone number many years ago.  I receive quite a few phone calls from such agencies for people who had my number a long time ago.

Someone from this number called me and did not leave a message.  I suspect that it is a collection agency trying to reach one of several people who had my phone number a long time ago.

Got a call from this number, and message at the same, spam?

Constantly calling for what I have no idea !
