Refund Of The Product - Amazon

I ordered a Beardo Sport Sunscreen Spray SPF 80 from Amazon on 15 August and received the product today. When I opened the package, I noticed that the sunscreen bottle was not sealed, which raises hygiene and safety concerns for a product that is applied directly to the skin. I requested a return through Amazon, but my request was rejected with the justification that the product is in good condition. For a cosmetic product, receiving it without a seal is not acceptable to me, as I cannot be sure whether it has been used or tampered with before delivery. I request that my return request be accepted and that I receive a full refund for this order. I would like this issue to be reviewed and resolved promptly.
