Called the number back a few times - busy until 1:00PM and got a message "We are not available - press 9 for more options" so I did. "If you would like to donate to our fund raising drive, press 1, if not and to end this call press 2"
Found this number on my answering machine today. I googled it and found another caller complaint website that said it was from a Breast Cancer charity. I bet it's the one that gives a tiny amount to the cause and pays itself with the rest of the money
