(Apex Legends) I need help with cross-progression and account merging.

So i played Apex Legends on my playstation 4 for a LONG time, but i used my parents email to link my PSN account to my EA account. I recently upgraded to pc but made a new EA account and started over again because at that time there wasn’t any cross-progression. Now i can’t connect my Pc EA account (new one) to my PSN EA account (old)

What i tried: Changing my PSN parents email to my current but it said the email is already in use.

And linking the same PSN account to my new account but it said it was already connected to my old one, it also said it the PSN could only be connected to a EA once in its lifetime.

When i wanted to remove the PSN link of my old EA account it said the progression can’t be transferred to a new account and you lose rights and subscription and a lot of more things.

Is there any fix? Thanks in advance!
