activation lock on and proof of ownership documents not accepted
I have got this iphone 12 Pro I bought refurbished for my granddaughter. Right now is an expensive paperweight. It is on activation lock and all documents I have as proof of ownership are either in pdf or in jpg.
Apple Activation lock team will not accept them either as pdf or jpg. This is an invitation to get me to try to start a go around process. All the official Apple stores nearby say they are unable to override the activation lock process. What else can I do?
iPhone XS, iOS 18
