Restore My FF UID

I would like to report an issue with my Free Fire ID and request the recovery of my account. I am the original owner of this account, which was created using Facebook and linked to a Gmail address and mobile number that I previously had access to, but I have now lost access to both. Because of this, I cannot log in to my Free Fire account. My UID is 8160947940, and this has been my main account for a long time. I have also spent money on the account to purchase diamonds. I know the Gmail address and mobile number that were originally linked to the account, but I can no longer access them to complete the login verification. Please investigate my account, verify my ownership, and help me recover my Free Fire account. I am willing to provide any additional information or payment proof required to verify my ownership.
