If you do not have access to your PUBG MOBILE account or any of the linked login methods, it is highly unlikely that you will be able to recover your account, @Artin.
If you have an access to any of the linked login methods or have access to your account, please contact the in-game customer service through "Help" located in the top-right corner of the login menu. You can also submit an Account Recovery claim to unlink compromised social media accounts linked to your account through there.
