Hmm.

So TODAY, when this number called, it was for something else....

Claimed to be the Lyons Club (with whom we work regularly through our non-profit). He didn't have the name of the person he wanted, he just wanted "whoever writes the checks"

Kind of a red flag. That's not how people solicit donations for real companies.
The second giant red flag was that he refused to take the email I offered him. Every other company soliciting donations asks for that, and usually sends an email. This guy hung up on me.

Clearly not Lyons Club. Avoid.
