missing heirloom and cosmetics

Hi, I’m looking for help recovering my original EA account that was linked to my PlayStation for Apex Legends.

I first played Apex on PS4 around 2019 and had progress, skins, and stats on that account. However, my PlayStation Network account is now linked to a different EA account that appears to have been created in 2023, and none of my original progress is there.

The issue is that I no longer know or have access to the email used for my original EA account, so I can’t log into it or recover it through the usual methods.

What I’m trying to find out is:

Which EA account (email) was originally linked to my PSN when I first played Apex

How I can recover access to that account

I can provide my PSN ID, approximate dates I played (around 2019–2020), and any other details needed to verify ownership. I also can provide screenshot proof that i played during 2019 with trophies i earned during that time

Has anyone been through this before, or can someone from support help check the account history tied to my PSN?

Thanks in advance.
