Finding old account

Hello A Marines Dad,

As stated in the program Terms and Conditions, you cannot transfer Credits between accounts:

You may not combine or transfer Rewards Credits with other’s Accounts. You may not transfer, sell, or perform any other action in any manner in violation or attempted subversion of these Terms and Conditions. Any attempt to combine or transfer Rewards Credits
will result in disqualification from the Program and forfeiture of all Rewards Credits in your Account. Microsoft reserves the right to take any other or additional action it deems appropriate in its sole discretion in the event that Microsoft believes (in
its sole discretion) that you (or you and others) have violated this provision.

Additionally, we can only handle issues with the Xbox Live Rewards program. For account issues, you may have better assistance by reaching out to Xbox support at (http://support.xbox.com/contact-us).

Hi,

If you cant find it, the only way to find it back its to call or chat with an agent, provide him the gamertag and he will check some security question with you to be sure that you are the owner. > https://beta.support.xbox.com/contact-us

Alrighty i did that thank you

You will need to contact xbox xbox Support to verify they can find it. Because i friend provide his CC information and support find a way to retrieve the account. But you will need to verify that.

There's no way to merge accounts. The best way of finding out if a gamertag is available is by trying to change your gamertag to it. The system will tell you if it's taken or not. You can search through the website, but it doesn't show tags that are in use
on other services.
