Refund request and appeal denied

I requested a refund on some of the items that my 12 yo bought and apple denied my refund request and the appeal that I made against the denial. The developers of the game agreed to a refund and asked me to initiate one via the mode of payment that I used, but apple denied my request. How do I make an appeal again? Is there nothing I can do now? Also attaching a screenshot of the game support asking me to reach out to them and of the issue.
