New iPhone 13, never used, I mistakenly got it from Noon and selling it

I bought an iPhone 13 from Noon 7 days ago and only opened the box without using it. I accidentally realized that I selected the wrong storage capacity, it turned out to be 128GB. I contacted Noon for return, but they refused because it's not completely unused, not at all, not at all, not at all. Check the purchase date. Today is August 16. What should I do? I want someone to buy it, never used, and brand new, in its original box and plastic wrap. Purchased price was 1800 Color: Black (Midnight) I'm in Jeddah, pickup in person or delivery outside Jeddah at your convenience. Check the photos, its price on Noon, and purchase date 👇
