I get calls from them ALL THE TIME and they never leave a message. It's CPYC and I can't find much about them, but this link is interesting. It outlines their expenses and income. If I'm reading it right, they spend (waste!) 63.8% on fundraising expenses. Maybe I'm looking at this wrong, but it looks like a loser of an organization!
Supposedly they're non-profit, but yet they don't have a .org domain. Their web site is www.calpyc.com. Maybe it means nothing, but I found it interesting.
10:00 Saturday morning after a late night out! Picked up at 4th ring and no one was there. Tried calling them to put me on their do not call list. All I get is busy signal.
