Hey KingOfWorld_03,
To clarify what's happened here, progress is stored on the EA account level, not on individual platforms like PlayStation, Xbox, Steam, etc. This means if you link your platform to a different EA account, you'll lose access to that progress. Your progress cannot be moved between different EA accounts.
In this case you'd need to move your PSN back to the original EA account it was on prior to this one, then try logging into that EA account from a PC platform like Steam/EA app. Moving your PSN to a new EA account would let you access that EA account content on PlayStation, not copy over progress from a different account entirely.
We are not able to make any changes to your account status or progress via the forums, but if something was linked or unlinked incorrectly it may be worth reaching back out to support to see if the original platforms can be re-linked.
