Can't Receive Otp On My Garena Free Fire Linked Gmail

I am writing regarding a problem with my Garena Free Fire Max game account linked to the email address gangster0***@gmail.com. On October 9, I accidentally unsubscribed from the sender address [email protected] in Gmail. I did not know that this action would stop OTP emails from being delivered to my inbox. As a result, I am no longer receiving any OTP codes from Garena, and I am now unable to log in to my game account. I contacted Garena customer support about this issue, but I was only advised to check my network connection, which did not solve the problem because the real issue is that the OTP emails are not arriving after I unsubscribed by mistake. I kindly request that my email address be subscribed back or reactivated for OTP delivery from Garena so that I can start receiving OTP codes again and recover access to my Garena Free Fire Max account associated with the email address gangster0***@gmail.com.
