How to unlinked 2 account

Hello,

I have 2 account that are linked onto the same ID, and i can't play on the PS5 and the PC at the same time.

Would it be possible to have 2 separate account in order to play on both device at the same time.

I would like to add that i have paid for the 30€ pack first then upgrade it for the 160€ package but i couldnt play with someone else for an unknown reason.

So i had to pay an extra 30€ to play on the PS5 when i didn't get all the coins that are in the packages.

Regards,
