Free Fire UID Hijacked After Account Binding

My Free Fire account with UID 1640188876 was compromised during the account binding process. I had given my login access to a friend so we could complete the binding, but without my permission this person changed both the linked Facebook and Gmail addresses. As a result, I completely lost access to my account and I cannot log in through any of my social media accounts anymore. I originally used this account via Facebook login, and all of my progress and purchases are tied to this ID. I have already contacted Garena Support through the help center, but so far I have not received a helpful response or any clear way to recover my account, even though this is clearly a hijacking situation. I request that my Free Fire account with UID 1640188876 be recovered and returned to me by restoring my original login access, or that I be given clear, step‑by‑step guidance on how to verify my ownership and reclaim the account. I would like this hijacking issue to be investigated and resolved as soon as possible.
