"Too many refund requests this year" from trying to refund Minecraft twice?

My mate recently bought Minecraft Bedrock and Java for £25, but never received either game, so he refunded it. After 3 days, he never got his money back or the game. He went to return the game once more, and was given the "Too many refunds this year" error, meaning that he lost £25, because he wasn't given the game...
Seems like an issue on Microsoft's behalf to me
