I have had luck having Amazon credit me back part of the purchase price when I need to repair what they sent me. Their chat agents have refunded me 20-30% of purchase price for keeping defective items like yours.
I got a hard-anodised aluminium oven tray which was bent at the corner. These things are solid, no way it was bent in transit unless it was by heavy machinery - if you slammed it in a van door I think you'd just break the door. Contacted seller and arranged a discount but it was a pain to do and going through the Amazon systems seemed janky. It was a case where the product worked, it was really just aesthetics, but I wasn't paying full price for a [factory] damaged item. Saved some product miles at least.
