First of all, you are posting to a user to user community forum. We are Apple users, just like you, trying to help each other with technical issues. So we cannot secure your account or do anything to it. Secondly, if you think you were hacked, you can check the Apple support page below for some helpful tips. But if you want help from us, we are going to need to know why you think you were hacked and what's going on with your iPhone. Details, please.
