Refusing to accept their mistake

I ordered few pairs of earrings via insta pg https://www.instagram.com/shonasstyle_?igsh=bzlwZXBtOW5lOHVu I ordered a peach shade but recieved blush instead. But the page is just refusing to accept their mistake and blaming it on filter n lights. I understand they play n important role but the product I received is clear not the one I choose.
