Activation lock removal declined. All papers aren't enough
I had my uncle try out an iPhone 8 of mine. When he told me he wasn't a fan of Apple devices and it was just too hard for him to blend in with all the features I wiped the phone but then the activation lock came out. Year later now I remembered this situation. Asked my uncle about all the Apple ID stuff he made, but he forgot them already, we did try resetting everything with no luck, Apple generated some iCloud email we can't get back to at all.
So I made an activation lock removal ticket over here at Apple and provided all the information with all the papers I got from purchasing the phone, but apparently it wasn't enough.
How can I remove this lock when Apple doesn't care about this and declines every ticket? How come all the papers I got from the purchase that are the only proof of purchase AREN'T ENOUGH?!
