Caller ID says Unknown Name, I called back and it says message box full.  No idea who it is.

Today, something about reducing interest on a credit card.  Just hung up to not waste any more of my time.  BTW I do not own a credit card.  Obviously a scam.

Call came @ 2:11 PM EDT on 08.14.2009 -- caller ID read OTTAWAHULL, ON, apparently originating in Canada. If I don't recognize the name or number on the caller ID whomever is calling is wasting their time because I don't answer.  I've been on the do not call list since day one but that list means absolutely nothing because it hasn't stopped the calls.
