online multiplayer suspesion

If you believe your account was somehow compromised then follow the instructions

here

Once a case review decision has been upheld then there is nothing you can do.

Yes I made a Case but they said that my suspesion still stands.

As Smwutches already gave you the website to get more information about the suspension: be aware that suspensions are issued by real life humans from the Enforcement team. From the time something was reported to the actual suspension, it can be several days,
as the Enforcement Team has to work through thousands of reports daily, and also has to check the report affecting your son for validity.

So whatever your son did, might have happened days ago.

Also keep in mind, that your son can also send messages through a smartphone app or from the Xbox website, without having to use the console. So maybe he wrote a message while you weren't around.
