Trade in policy / Required condition of the old phone while trade in
I have an iphone 7plus which I am using to trade in for an iphone 11. I am concerned if the trade in will be accepted or not as though my phone matches the basic description for working condition but I have other issues in my phone. Like my phone's body is slightly bent. I have a very tiny colour patch on the display if you see it when you see it over a complete black background. It says if not accepted then I will have to pay at the spot which I am definitely not happy about, if it wont accept my old phone it should tell me before hand not at the time of delivery along the new iphone.
Please help.
Thanks
iPhone 7 Plus
