Sorry to hear that your account has been compromised, you can try to recover it following steps here:

My account got hacked and the hacker set up two factor authentication. I found out that this hacker is also using my account to scam people texting my. Friends. But got back but i am and now I can't not text my friends

I really understand your situation. I have seen several users losting accounts for hackers. I can only suggest you in the future to setup two factor authentication on your account - preferably a phone number to receive SMS or an authentication app. This decreases your chances of being hacked to almost zero.

First of all, you might want to go to https://account.live.com and change your password.

Then further down the page, enable Two Step Verification and set up the free Authenticator app on your smartphone.

With Two Step Verification enabled, a hacker would have to actually physically steal your phone as well as your new password to get into your account. With the Authenticator app, a hacker couldn't get into your account just with a stolen password.

After you made your account hacking- and theft-proof, you can try to contact the official support at
https://support.xbox.com/contact-us and ask if they can refund that unauthorized purchase.

Your brother is always responsible for what happens to his account. After he got hacked once, he should have taken the necessary steps to prevent further hacking, by
changing his password and turning on Two Step Verification and using an Authenticator App.

With Two Step Verification in combination with an authenticator app, a hacker wouldn't be able to get into your brother's account, as the hacker would have to physically steal your brother's phone. It's basically like letting your entrance door unlocked,
and then complaining that a burglar got into your house and stole your TV.

Your brother can try to do as Mistress Sara said, and contact support to file an Unauthorized Account Access, and then file a Case Review on the Enforcement page at
https://enforcement.xbox.com

But FIRST your brother has to make sure he changed the password to something secure and enabled Two Step Verification in combination with the Authenticator App.

Also, while on the
page for account security, your brother needs to check that the hacker didn't add a phone number or email that belongs to the hacker. Otherwise the hacker would simply recover the account through his own emails or phone numbers.
