Who called from 4193242777

Called this afternoon, left no message.

Called 2x no message... Returned call it is the American Red Cross

Got a call tonight. Did not answer and because they didn't leave a message, they won't get a callback. If I can't determine who is calling me, I don't want to talk to them.

It's the Red Cross wanting to sign you up for a blood donation, shortly prior to the 56-day mark (earliest date you can donate after prior donation).
