I have received texts from people saying they have missed facetime calls from me when I have not called them. Also, today y girlfriend received a facetime call from me and when the call connected there was a woman staring back at her. She immediately hung up and when it called back she ignored it. It says on her call log that it was me who facetimed her. how could this have happened?
Seems to me your apple id is compromised and someone else is using it. Though I don't know why they'd call people in your contacts list. I'd suggest resetting your password ASAP!
