I've gotten calls from this number (and from numbers one or two digits off from it) for the last several days). After reading other comments here, I called the number back and asked not to be called again. Well, today, I got another call and when I answered, the guy started a very rapid pitch for Oxfam America. I interrupted to tell him that I had requested not to be called, but he just started talking louder and faster. Does Oxfam America (or any other non profit  that uses this service) REALLY think that they will get more donations by having obnoxious people making telephone solicitations??
