Account hacked then banned, I can still access it but the email was changed.

Hello

I haven`t played the game for 2 years and when I tried to access it through my PlayStation account it said that my account was banned.

I managed to log into it but my email address was changed by someone from South Korea (see attachment) and he also linked his steam account. (I only played the game on my PS4).

I am confused about how I should proceed, if I recover my account will the ban be removed?  And I have another problem, when I try to open a case and then look through my cases it says taht "You currently do not have any cases with us".

I have access to my former email, the card that I used to buy the battle pass or any information that could prove that I am the original owner.
