Greenpeace is the Organization --> Repeat calls, multiple calls per day, no messages left. EXTREMELY ANNOYING. Greenpeace will no longer be receiving charitable donations from me, since they clearly spend entirely too much of their operating budget on calls to solicit donations.
Gotten a call from this number tonight and past three days, all at different times. Answered the first time but hung up when I realized it was automated, without catching who it was from. Just called the number back and was greeted with a recording identifying it as Greenpeace. Left a message on their voicemail asking them to take me off their contact list.
