A couple of years ago my brother game me his Xbox as a gift. The gamertag has his OLD hotmail address that he has forgot the password and his security question. He doesn't remember any of his contacts he sent emails to, subject lines etc. Therefore it is UNRECOVERABLE using the password reset form. We have tried several times.
I have a full purchase history details since he gave me the Xbox and cards used etc.
Put simply is there anyway in which Microsoft can change the Microsoft account associated with the Gamertag without knowing the password?
I have accumulated nearly 19k Gamerscore, purchased several DLC games, map packs and the like worth well over £200. I really would not like to create a new one.
