Where are my 50 free Butterfly Points?

Several times recently I have endured popup ads on Care2 telling me how I have "earned 50 free points" for some action or another.  However, after putting up with this drivel, my points never appear.  I'd like to plant a tree with those points....I wonder if the 200 trees I've spent points on are reallly planted?  i know the foundation listed exists, and that Care2 is listed as a donor on the tree polanting organization's website....but it would seem that the level of sponsorship listed by the oganization should be higher IF all trees given by Care2 users are really donated.  Care2 has not provided any documentation at my request.
