Out of curiosity I called this number back. Much noise in the background, guessing it is a call center. Someone finally said hello, I asked who it was and woman answering had heavy accent, so heavy I could not understand what she was saying. Am relegating this one to the block pile.
The Caller ID said American AFF. A quick google cAME UP WITH THIS:
"America's Future Foundation exists to train the next generation of conservative leaders and winning the hearts and minds of young Americans."
Boy did they call the wrong number! Blocking. With extreme prejudice.
