EA Connect Compromised and wont unlink

Recently I logged into swgoh on my Pc client only to find this little droid asking if i’ve ever played mobile. To my surprise, my ea connect was disconnected from my Swgoh account. Turns out somebody miraculously logged in via ios (im android btw), and managed to not only log in to my account, but unlink my EA account and put theirs in! I know they logged in via ios because my guild mates messaged my account and they responded going clean with everything. However i’m unable to unlink their ea connect account, and was hoping for someone to help me out and unlink their account so I can put my ea connect in again!
