Unable to Update Account Security Settings

They told me this

Account security is a top priority at Microsoft, and we have a team dedicated to investigating and validating fraudulent activity. The account and billing activity associated with your Microsoft account was thoroughly reviewed by our fraud team, and I can confirm there was unauthorized access to your account. Unfortunately, during the investigation process, we found that your security information has been changed.

Unfortunately, when security features are updated on an account, we are unable to assist with an account recovery as these types of updates and/or removal are completely out of control of customer service. We are unable to make any changes to the security information on the account due to security protocols set up and the acceptance of the Microsoft Services Agreement when the account was created.

The only option we have is to permanently suspend this account to prevent any further use. At this time, I have successfully suspended this account, and this will remain on indefinitely.

?Thank you for your understanding and patience during the investigation of your account.

Sincerely,

Microsoft Support

I tried getting the account investigated but only for the result to end up like this.

Hello there,

Thank you for posting here on the Xbox forums. Looks like you are unable to sign into Xbox.com. Have you tried using a different device to sign in? Also, would you mind typing out the error message you are getting? I am unable to translate the picture unfortunately.

Aside from that, I would try
updating your Password and your
Security Information.

Hope this helps!

Probably something to do with the security settings on the account.

I would sign in, go through all the settings (not just the security), make sure everything is set correctly and updated.

Hey there!

Due to inactivity we will be locking this thread.

I understand it is frustrating that you are unable to access your account while your security information is updated. For future reference, just keep in mind that it's best to have

updated information on the account including secondary emails/phone numbers.

We hope this helps.
