Free Fire OTP Not Working After Hacker Changed My Linked Email

I am having a serious problem with my Garena Free Fire account that is linked with my Google account and email address “nadeemsheikh***[email protected]”. For the last 5–6 days, I have not been able to log in to my Free Fire account properly. About 14 days ago, my Free Fire account appears to have been hacked and the email linked to the account was changed without my permission. Now, when I try to change the linked email back or recover my account, the system asks for an OTP, but I either cannot receive or use the OTP correctly, so the process does not complete and I remain locked out of my account. Because of this issue, I cannot access my Free Fire account or manage any account settings. I request that my Free Fire account be recovered, that the unauthorized email change done by the hacker be cancelled, and that you either send a working OTP to my email or help me safely change or update the linked email so that I can log in to my account again without any problem.
