Restore old Microsoft account?

I used a Microsoft account on my Xbox 4 years ago today I got my old Xbox 360 out of my closet again so I can play a few games with my old score but I forgot my data and I do not have the email either more. The support can't help me either, but I have given the same phone number on each email and do not know how to restore my account now to be able to play again for a quick help Best regards Mario

Create a new account and play until the old score. And then do not make the same mistake again.

You're funny you fish age I want to have my old things and my old contacts again

Did not you save the data of your MS account somewhere in the PC? I'm afraid your old and vegessenes MS account can't be reactivated without data such as account name, eMail, Tel.Nr, … Ricardo

No, unfortunately I do not have them in my PC if I only knew my Gamertag then everything would be much easier… So I have given a number but I have indicated in all my Kontoa
