Erroneous purchase
Hello. My brother made an in-game purchase for $ 10 and I would like to return the money. I tried to return via reportaproblem.apple.com, but I was constantly receiving messages "At the moment we are unable to process your request. Please try again later." or "Refund for this purchase is not possible.". What to do, tell me?
