I'm sorry to hear that you were scammed. It's important to be cautious when dealing with online transactions, especially when it involves personal accounts or sensitive information.
In this situation, it's crucial to report the scam to GCash immediately. You can contact their customer support to explain the situation and provide them with the necessary details such as the scammer's phone number and account name. GCash may be able to investigate the issue and possibly help you recover your funds.
Additionally, it's advisable to refrain from sharing any OTP (One-Time Password) with anyone, as scammers often use this information to gain unauthorized access to accounts and conduct fraudulent activities.
Remember to stay vigilant and verify the legitimacy of any transactions or offers before proceeding. If you have any further concerns or questions, feel free to ask for assistance.
