Is there any possible way for me to get my information?

Hi Carmello! My name is Darhlene and I’m here to assist you.

I'm very sorry to hear about your current situation. I understand your frustration but, don't worry, I will help you get this sorted out.

Since you have lost access to your account, I highly recommend filling out an account recovery request. When you do, please take your time to provide accurate answers to the questions asked on this link:

Please wait for at least 24 hours after submitting the request to get a response from Microsoft.

Kind Regards,

Check ebay. Sometimes people do sell stuff like that there.

Ebay is your best bet. There may even be sites that sell the boxes for those who like to collect the actual boxes to consoles.

My son thinks he deleted the saved information that made him a higher rank. Is this possible, and if so, is there any way to get it back?

Hi, my name is Marvina and I will be happy to help you.

I'm sorry you have this problem, researching on the internet I was able to find that in the forum, independent advisor Laura recommends the following steps for a solution.

In order for you to recover access to your Microsoft account, you must answer the Microsoft Account recovery form where a series of questions will be asked that you must answer. When you have had the score accepted by the server to change the password and access the account.

Note: The person who has access to the new validation means will be able to cancel any recovery process that is attempted, because they will be able to confirm the requested verification codes.

While filling out the form, we recommend that you keep the following information in mind that may be of help to you:

During this process, reply to the registration from a trusted computer or device that you're signed in to from Outlook.com.

Also, make sure that the data you entered when creating your account is as accurate as possible.

The form will ask you for message subjects and email addresses of other contacts. In this case of not remembering any information from the messages, check with your family, friends, study or work colleagues, if they have any email so that they can inform you of this information.

When you finish, the system will assign you a registration number that will be important to us. You will be able to see it in the secondary email that you added during the form and you will also be able to view it at the end.

Also, we recommend that you establish communication with XBOX support so that they can inform you if it is possible that while you recover the other account, you can transfer your Gamertag to another account and likewise the additional folders.
