Re: 'Free trial expired', despite playing on EA Access.
I'm unfamiliar with EA Access on PS4, but on Xbox and Origin Access on PC last I'm aware of you do need to "purchase" (for free with EA/Origin Access ofc) the game through the store to be upgraded to the full version from a trial version, so I would assume that to be the case on PS4 as well, though I'm unable to confirm it unfortunately.
If you plan to continue the route of contacting EA support I would recommend using EA Live Chat as personally I've usually found that the most helpful when I've had issues.
