Dream Makeup — Return/refund request was not accepted for unused products

I ordered makeup products from Dream Makeup website. The order was delivered on 21 September 2026. The products are unused and in their original packaging. I want to return the products and get a refund, but I am unable to contact the seller. Their customer care number is unreachable and my email/contact attempt has also not received a response. The website mentions a 7-day cancellation/return policy. I request assistance in initiating the return and obtaining a refund.
