I have eMailed and written to the Metropolitan Musuem of Art, with a transcript of the comments from this page, suggesting to them that IF they have contracted out their fundraising, they should get a NEW contractor as the present one is most unprofessional and annoying...I too am a member of the Musuem and I do not appreciate all the calls, at all hours, with no messages.  Here is the Metropolitan Museum of Art contact info:
