There is recent activity on my account with a gameI do not have

I HIGHLY suggest you right now go and change your password. You are best also to set up two step authentication.

Click me

After that contacting support via
THIS and inform them of the strange activity and they can help you see if anything fishy has happened.

Also please go to settings. Personalization- My home xbox, and make sure your system is set as home for your gamertag.

Sorry to hear that you having an issue.

If you think that there are suspicios activitys on your account you can check https://account.microsoft.com/security. There you get an option to check who was logged in to it.

Also i recommend a change of your password and setting up the two step authenification. Hope that helps.

In addition to what's been said, I would also recommend using a trusted authenticator application. Account security is important.

if you have recent activity not from you then someone else has access to your account, change your password and add two step authentication

Thanks, the gameis now available.
