Free Fire Recovery Email Changed by Hacker Without Account Owner's Consent

I am having a security problem with my Garena Free Fire account. Someone changed the recovery email of my account without my permission, and now another person is playing on my Free Fire ID with the nickname “@ᏦҒㅤSʟᴇᴇᴘʏ乂晝”. I cannot change the recovery email back or secure my account through the usual options. I kindly request that my account be secured and that the recovery email be changed according to my instructions so that only I can access and control this Free Fire account. I want to prevent any further unauthorized use or changes.
