Xbox to online linking fault

[goatyzentura]

Hi,

I have set up my account to get online with medal of honor warfighter battlog, once done I thought that the link between my Xbox play and online stats would be sorted but havefound that when login in on my Xbox to medal of honor 'Origin' signs me in automatically under someone else's name! (Tom.woods278@gmail.com) and I can't log out to log in under the correct name!? Can you help??

Jael.
