Can't Access My Original Garena Free Fire Account Through Gmail

I have a problem with my Google‑linked Free Fire account and I am requesting support. My Free Fire account, which I use with Gmail login and has the in‑game ID 7759689978, no longer shows my previous game progress. When I log in with the same Gmail, my old account data and progress are missing. I last successfully played with my old Free Fire account around June 20. After that, when I opened the game again, my progress was gone and I could not access my old account. I tried clearing the game data, but this did not help and my previous progress still did not return. I have spent around 90,000 (local currency) on this account through Google, and I have payment receipts that show my purchases on this Google account. Because of this, losing access to my old account and all related purchases is causing me serious concern and frustration. I kindly request that Google investigate this issue related to my Gmail‑linked Free Fire account and restore my old account and all its progress and purchases linked to this Google account.
