I just loaded my GCash AmEx account. While I did receive the message of the load, immediately after my account was deducted 1,414.14 pesos. There's no context of why I was deducted this, nor any transaction summary. I've tried reaching Globe in all their fields but they just passed me around. Now I'm really pissed at globe and this is my last resort..
The charges can be from auto-charge subscription from a certain website, be cautious on signing up with website offering free access to premium content, it will asked for your debit card details then later on billed you with corresponding charge after your free trial expires.
To further clarify where the charges came from you may check your Gcash Amex transaction logs and request for a refund if deemed necessary
