My Facebook Account Was Hacked - Help Me!

I am writing about my problem with my personal Facebook account, which I have been unable to access since it was hacked sometime between 2022 and 2023. I live in Narayanganj, Bangladesh, and I was using Facebook only for personal use. The account was registered with the phone number 01727707***.  After the hacking, a person who appears to be the hacker contacted me and said that they wanted to buy my account, asking if I would sell it. This made me very uncomfortable and worried about the misuse of my account and my personal information. I kindly request that my hacked Facebook account be recovered and returned to me. I also ask that any unauthorized access be blocked so the hacker cannot continue using my account.
