Sending time and date stamped pictures of the phone would have been helpful however it could be suggested that this is what the phone looked like when that particular photo was taken but not how it was recieved by Samsung.
It's an unfortunate situation to be in.
When I traded my phone in with Samsung last time I did this in a Samsung Experience Store so none of that happened to me.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help.
