Apple Services deducted money from my Gcash account without my consent

I downloaded an app called “Prequel”. It has a 3 day free trial and this is what I selected. After a few seconds, Apple Services deducted 259 pesos from my Gcash account. Usually, when doing transactions, gcash would usually ask for a confirmation message or send an OTP to confirm but apple services just deducted immediately. This has been the same problem that apple users are suffering even from before. I want to get a refund and delete the app Prequel
