I just received a revised trade in offer for my iPhone 12 Pro Max I traded in (in excellent condition, no cracks or issues). They are saying that they don’t want to give me any money, and the reason listed is “Multiple cracks/shattered display, cracked Chin Plate”. First of all, my phone wasn’t cracked at all, but secondly, I don’t even know what the Chin Plate is, can anyone help me figure out what that means?
