I've never donated to USOC. I don't know how they got my number. (And most recently called on a Sunday afternoon!!) But. I called the number back and followed instructions to remove my number from their calling list. I just had to listen to their Olympic spiel first.
I receive a call from this number at least twice a day. I do not answer mostly because it only rings a couple of times. However after reading the other comments I will not answer.
