I think they've taken over from environmental defense fund as the most annoying solicitor.
They called 4 times in 2 days from 4 different numbers:
(571) 441-0119
(571) 441-0107
(571) 441-0099
0115714410056
The top 2 came through callerId as "UNKNOWN". Sorry, but if you care about donors you
1) will not annoy them this many times
2) have a callerID show up as UNKNOWN
3) have a callerID that displays as an international dialing code going to COLOMBIA
