Linked to someone else’s EA account

I think we need someone within EA to manually remove the linked console from the other persons EA account. I’ve made this EA account for my PlayStation, but am unable to link to my console while someone else is linked. The linked EA account to my PlayStation is a gmail that starts with “st*****@gmail.com”, which is one I have never seen or created. I tried calling playstation, and was told there is nothing they can do, and to contact someone from EA. I feel like I have no option because I have no one to contact, and need to create a new PlayStation account. But when I’ve been collecting games since 2015, this feels like a very bad idea. EA needs a support team.
