Garena Free Fire Account Hacked and Email Changed Without Permission

My Garena Free Fire account named RUBELAHMED with ID 1423989742 was hacked about three months ago. After the hack, the email address linked to my account was changed without my permission and I was logged out from everywhere, so I can no longer log in or reset my password. Since then I have not been able to access my account at all and I am very concerned about how it is being used. I am the original owner of this account and I want to recover it. I request that my old email address be restored to the account, or that the hacked email be removed and my access be returned to me after verification, so that I can use my account again safely.
