Block them they have changed their number I have received 120 unwanted calls from them and they know you can not stop them. I blocked their other number 888-322-8209 now they are using this one.
They may be "legal", but that doesn't mean what they're doing is ETHICAL. It isn't, and they dang well know it.
Try to call them to get your number placed on their permanent do not call list. They don't have one. And the person you talk to, if you can actually get someone to talk to you, is always very snippy and rude.
EVERY other legitimate charity I've dealt with DOES maintain a permanent do not call list. They are more than happy to put you on it, and they will NOT call again, if you ask them not to.
Not this one. Bottom feeders. As close to a scam as you can get and not be a scam. Block 'em!
