My son created his gamertag and account several years ago. This weekend it has asked him to reconfirm his microsoft account and password in order to let him onto xbox live. Unfortunately, since the account was created we have changed ISP and hence email addresses so we
a) know the original email account linked with the gamertag but not the password
b) can't use the password reminder service as it sends an email out to the address that no longer exists
c) can't use the recover account process as the email address is so ancient that I do not have enough info on it to convince the service that it was ours.
Surely there is some way for me to prove the gamertag is ours and get it switched to link with one of our current email addresses?
I can give the credit card used to activate the Xbox live account and all recent payments, but have no idea who to contact or how to request this.
