Free Fire Guest Account Recovery Request for UID 6964646522

I am writing regarding an old Garena Free Fire guest account that I lost when I changed my device about five years ago. The account was not linked to Google, Facebook or any other platform and was only used as a guest account. I can no longer access this old account on my new device and would like it to be recovered if possible. I am sharing the information I still have about the account, including the player profile with the username “Burg1C9l9v7w” and UID “6964646522”, so that you can locate it in your system. I kindly request that my old guest account be restored or that you inform me clearly if recovery is not technically possible. I would appreciate your support and a detailed response about what can be done in this situation.
