I'm leery of anyone who calls asking for money. Particularly if they want a credit card number.
It may or may not be legit. That's the thing with unsolicited solicitors. You don't really know.
I prefer to give to organizations that I know.
Sometimes I'm more suspicious than I should be I suppose, but phone calls are on the top of my "Damn, This Is Annoying" list.
I have a phone for my convenience, not theirs. Scam or not, I don't give them money.
