Fraud
i was going to sell my iPhone 7 Plus, and a man lied to me. He asked me to see if his icloud will work on my iPhone, so I logged in to his iCloud, but he changed the password... now I can not log out. Is there a way to log out of his ICloud if I know the Apple ID that I used on my phone before he did this thing ?
iPhone 7 Plus, iOS 13
