Free Fire UID Inaccessible After Facebook Account Loss

I am writing because I have lost access to my Free Fire account that was linked to my Facebook account, and I would like your help to recover it. My Free Fire UID is 1521214121. About one year ago, I lost my Facebook account, and since then I have not been able to see or access my Free Fire account that was linked to that Facebook. I have tried to reach out for support but have not received any response, and my account is still unavailable. I have been unable to use this UID for a long time and cannot enter the game with this account. I kindly request that you help me recover my Free Fire account which was linked to my lost Facebook account, and restore my access to it so that I can continue playing.
