I Lost My Old Phone, So My Free Fire Guest ID Also Got Lost

I am writing to request help regarding my Free Fire account, which I have lost access to after my old phone was lost. My in‑game name is {DJ}Dheeraj@ and my Free Fire ID is 1799293096. This account was created as a guest ID on my old phone, so after losing the device I can no longer log in to my account. Because it was a guest account and my phone is lost, I am unable to use any normal recovery options and I cannot access my in‑game progress anymore. I am very attached to this ID and have spent a lot of time on it, so losing access has affected me a lot. I kindly request your support to help me recover this Free Fire ID on my new device and secure it from any possible misuse. Please guide me on the steps needed and what information I should provide so that you can verify that this is my account and restore my access.
