Garena Free Fire Name Changed and Contacts Deleted

I play Free Fire on an Android device and my game account has been hacked. Someone gained unauthorized access to my account, changed my in‑game name to “亗ＣｒａｚｙＢｏｙ❤乂” and removed all of my contacts. Since this incident, I can no longer use my account as before and I am very worried that my game progress and social connections in the game will be permanently lost. This situation is not caused by me and I believe my account security has been compromised. I kindly request that my Free Fire account be recovered and secured, my previous data and contacts be restored as much as possible, and the hacker’s access to the account be completely blocked. I also request information on any additional steps I should take so that such a problem does not happen again.
