Unauthorized Deduction On My Gcash

I am a GCash user in the Philippines and I want to report an unauthorized transaction on my account. On September 22, 2026 at around 4:10 PM, an amount of ₱699.00 was deducted from my GCash balance for a transaction with the merchant “HONG KONG VCREA” with Reference No. 804843492. I did not authorize or make this transaction. I only discovered it after checking my GCash balance and transaction history. I also received a message that my GCash account was successfully linked to Temu, even though I did not intentionally link my account or approve such a connection. I am using GCash on an Android phone and I am concerned that my account may have been compromised. I want to request that this specific ₱699.00 transaction be investigated and reversed if possible, and that any related merchant link (such as Temu or HONG KONG VCREA) be checked and removed if it poses a risk. I kindly request your guidance on the proper process and requirements for a refund or chargeback for this unauthorized transaction, and I also ask for your help in securing my account against any further unauthorized charges, including any security checks or steps I should follow.
