Unable To Access My Google Account

I am a Free Fire player from India and my game account, which is linked to my Google account, has been hacked. When I try to log in now, instead of opening my old account, it opens as if it is a completely new account. On my original account I had topped up diamonds and also owned old skins that I obtained earlier in the game. I am very upset that I no longer have access to this original account and to the purchases and items inside it. I urgently request that you investigate this situation, recover and show my original Free Fire account linked to Google, and restore all my diamonds and old skins. I also ask you to secure my account against any further unauthorized access so that this does not happen again.
