hiw do i get my phkne back under my control
My phone’s software has been upgraded to iPhone 12 by a person with a Mac Sierra. The message on my phone says third party controls my phone. I have about five devices and six different cellular companies on my phone. Third party uses the companies at different times. How can I get my phone back to factory strings? Mac IOS High Sierra is the hacker in my ohone. He is bleeding me dry. Opening up accounts at stores, emptying the cards on my acct. including bank. Please someone tell me what to do. Apple has done nothing.
