Hello! I'm sorry to hear about your situation. It's important to stay cautious when dealing with scams online. If you're having trouble finding someone's Facebook account, here are a few steps you can take:
1. Try searching for the person's full name: Make sure you're typing the exact name of the person you're looking for. Sometimes, using variations of their name or adding other details like their location can help narrow down the search results.
2. Check mutual friends: If you have any mutual friends with the person you're looking for, you can ask them to provide you with a link to the person's profile.
3. Search using email or phone number: If you have the person's email address or phone number, you can try searching for their Facebook account using that information.
Regarding the Gcash account, it may be challenging to find the exact user information associated with a specific phone number without proper authorization. You can reach out to Gcash customer support and explain your situation to see if they can assist you in identifying the user of the account.
Remember to be cautious when sharing personal information online and when dealing with unknown individuals. If you have any concerns about potential scams or fraudulent activities, it's best to report them to the appropriate authorities.
I hope this information helps you in your search. If you have any more questions or need further assistance, feel free to ask.
