This number calls at least once a week, but never leaves a message.  I believe that it is OSU looking for a donation.  I paid enough for my daughter's tuition.

Called, left no message.  No clue who this is and called id comes up as Unknown.

This caller left no message.  Legitimate callers with a real need to speak with you leave messages.  This call is suspicious.
