I need a refund and when I click in it comes out in a different language I already tried fixing it. I went to regional or country, and still the same language comes out.

Wondering if this Apple ID support article (link below) may be helpful:

Request a refund for apps or content that you bought from Apple – Apple Support

or

If it is an Apple Pay purchase / refund

If needed:

You might want to reach out to Billing Support :

There's a "get Support" link (online chat, phone, eMail etc) at the bottom of their website (link below)

Find answers to your questions about purchases, subscriptions, payments, and billing:
