I answered inadvertently when call forwarded to my cell. Lady asked for my s.o. by name, said she would talk to me. I asked what organization and she said "Diabetes Fund." I asked her to send us snail mail as all of our non-local charities are by mail. She said they'd send. I won't hold my breath.
Caller ID says "NAPA" (Napa valley?). They leave no message.
I call after hours (using *67 to block my number). The phone "message" on their answering machine is just about 3 minutes of silence. Then it hangs up on you.
So we have a spoofed caller ID and the inability to be called back. Smells like a SCAM to me.
