I bought 4 iPhone 12 in may 2022
How do I drop the iPhone account and get my money back?
👉 Contact the store or seller from whom you purchased the iPhones and ask your money back.
If you bought 2nd hand iPhones, they are not hacked, but those iPhones are still locked with the Apple ID of the previous owners who did the setup.
Activation Lock prevents anyone who is not the owner from using this iPhone.
