Just going through that myself. My son's Microsoft account was hacked, we contactes customer service and all they did was acknowledge the account was compromised, close it indefinitely asking us to buy the game again, and locked my account as the family manager. Fortunately I am a Linux guy and the last Microsoft thing I've touched was windows xp some 20 years ago. But imagine thinking this is acceptable?!

I guess they still suffer from monopoly syndrome. The EU should get them again.
