Microsoft account recovery form

Hello, so basically, I've been "locked" out of my Xbox/Microsoft account ( I'm using a different Microsoft account to message here), and It's asking me to go into the account a change the password, however It says I need to verify that it's me. The first problem that I am having is that the verification email that is linked to my locked Microsoft account is an old one and has been disabled so I can't do that unless it's possible I can get it changed. The next Problem I have been having is with the Account recovery forms. I've done at least 10 plus off these, I put in the 100% correct information, I give it my Xbox username, the the Xbox device ID and I also provide the credit card details that I have used on that account for proof. However the Automated system keeps declining me. I've got to the point where I literally put all the correct information I can, I have no other information that I can use for more proof. Is there literally ANY possible way I can get someone to change the verification email for that account to my new one so I can get in please. The account recovery form isn't accepting me, even though I'm putting enough and the correct information in for proof.
