Re: "I need a refund and when I click in it comes out in a different language"
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
How to: Get a refund for purchases made with credit or debit cards using Apple Pay - Apple Support
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:
Subscriptions and Billing - Official Apple Support
or
See a list of Apple phone numbers around the world
Contact Apple for support and service – Apple Support
All the best :-)
