Free Fire OTP Not Received After Unsubscribing From Garena Emails

I am writing about a serious problem with my Free Fire account on Garena. My player ID is 2805565044 and the email registered to the account is s871867**@gmail.com. My account appears to have been hacked and I can no longer access it. I am trying to recover the account using the recovery options, but I am not receiving any OTP or verification emails from Garena to my Gmail address. I accidentally unsubscribed from Garena emails in Gmail, and since then I do not receive any messages from Garena, so I cannot complete the recovery process. Because I cannot get the OTP, my hacked account cannot be recovered or secured. I am very worried that the hacker will continue to use or damage my account. I kindly request that you reactivate or resubscribe my email address to Garena communications, ensure that OTP and recovery emails can be delivered again, and help me recover and secure my Free Fire account linked to player ID 2805565044 and email address s871867**@gmail.com.
