my account got stolen and get banned by a hacker and i explain my issue in community support and get rejected !!
Solution
As long as an account is found to be cheating it will be permanently banned, regardless of who was on the account at the time. It is your responsibility as the owner to ensure your account remains secure.
If your ban appeal submitted through https://pubgmobile.live/support was rejected, that means your account will not be unbanned.
