email account renamed in error help


New Email
I was prompted to create a new email address for my xbox account but when I was done I was informed it was just changing my current accounts name.
I received an email stating if you do not want this go to to change the account name back.
However when ever I try it will not allow me to fix this.
I need this account to be renamed ASAP its my main account for emails.
Can someone help me correct this mistake?
