Hey Chaoscore,
Your brother can request a refund if he’s purchase a game or a subscription in the wrong region, via the self service page that we have:
https://us.support.blizzard.com/en/help/product/services/334/1997/solution
Please make sure that he remains on the US site, in case he’s redirected automatically to the EU page. We do answer every ticket that we receive, and you can also check the responses to your tickets from your account management, if necessary:

Hope this helps! :folded_hands:
