Someone else's EA account is connected to my xbox?

I've had a xbox for a few years now and I just now realize the reason I cant play madden onlinr is because my "EA" account is disabled but whenever I try to fix this issue I see that the EA account shown is under someone else's email and not my account. 

Id be intrested in getting a response and being told on how I can fix this problem and connect my EA account and remove this random persons EA account.
