hmmm i have no idea how to contact the mods.
by that error message your psn account is already linked to an epic account.
probably you did that by mistake and now don’t know which account it is.
or maybe you’ve created a new account.
i think you should try and contact customer support if that exists.
or try logging out from epic and logging in using psn, then go you should be logged in, and then go to the profile and check which account it’s using.
