Just block them. It is a scam robocall that is programmed for voice recognition. I wanted to see if it would put a live person on by giving confusing answers to the machine. Instead it jumped past its programmed listings of points and right to asking me how much I wanted to donate. Still have no idea who they are. The machine just hung up instead of getting a live person.
