My refund request was rejected twice. Is there a way to have the decision reviewed by an Apple Support advisor?

The purchase was made on August 16th, but I only noticed the charge on August 22nd. It was an unwanted purchase that my little brother accidentally made while using my device. I did not realize the purchase had been made at the time, which is why I didn’t request the refund immediately. As soon as I noticed the charge, I submitted a refund request, but unfortunately it was rejected twice. I understand that the purchase was made several days before I noticed it, but I genuinely did not authorize or intend to make this purchase. I would really appreciate it if a human advisor could manually review my case and consider a refund. The money is very important to me, and I would be extremely grateful for your help.
