Free Fire OTP Not Receiving After Unsubscribe - No Support Helpline Number

I am a Free Fire player from India and I use the account with the nickname ISMART BABA and UID 3077343887. My account is linked to the email address krishkash9***@gmail.com. Around 27 November, I accidentally unsubscribed on the Garena account / email side, and since then I have been experiencing problems with OTP codes. Because of this mistaken unsubscribe, I am either not receiving the OTP or it is not being sent correctly, and I am having difficulty accessing and using my Free Fire account and related services. I have tried to contact support and requested help to resubscribe, but my problem has still not been resolved. I kindly request that my email address be resubscribed to my Garena / Free Fire account and that the OTP sending issue be fixed as soon as possible so that I can normally receive OTP codes and use my account without any problems.
