Received a FaceTime call from unknown person I have received a FaceTime call from unknown source. I'm not sure who this person is, nor do I know the caller's email.

What can I do? I don't want unknown people contacting me. It was from an iCloud email address.
Block that caller! And if he or she calls again just contact Apple and they will help you resolve the problem! Just follow my steps and you will be fine!
