I cant get my ea account to be unlinked from my psn due to a ban

The ban reason for your PlayStation is important if you got ban for cheating or lag switching ea won't do anything but if you got ban for a reason like I don't know being toxic maybe you can contact ea support and ask them to unlink your ea account from PlayStation (as I know the data of your account (skins, heirloom, apex coin etc.) won't be transformed to another account.)
