Téléphone

Hello to the whole Microsoft team I changed my phone number and I'm giving myself the new one the problem is that I put the new one on our account and I can't have an account is that Is it possible to change my phone number with the new phone number I like

Posted telephone number at the end of the month and is no longer valid and I get the new one that I registered but I can't get it because they tell me that I said registered on the other account on small problem that from this account I have my console and my games and I bought thingsI have already lost my account precisely because my telephone number and my email address was blocked because I no longer remember the password

Thank you

:)
