I missed this call and called back as soon as I could only to receive the message "Thank you for calling the fund raising center. We are unable to take your call at this time" and then nothing.
They called asking for Deloris and when told I don't know who that is, they responded with "that's okay. We are calling for either one of you" before going on some donation rant. It may have been a realistic sounding robot, or a crazy person. Either way, it screamed elder scam. Don't give them money.
