Caller ID says St Judes. They call at least once per day, every day. I've already blocked the number, so they don't even get my answering machine... but still they call.
I donated to them once. I never gave them my number, and it's unlisted, so I don't know why they think I'd appreciate a phone call from them. Constant, unrelenting harassment is a very strange way to thank a donor. I realize that they are exempt from the DNC rules, but it is not in their best interests to anger the people who support them.
