I purchased an app on app store using my VISA debit card, the app cost is 1.88 dollars. my fund in my debit card is only 1 dollar, the purchase was completed/succesfull, how could that be possible? and what would happen next? will apple collect the amount when I added fund to my debit card?
EDIT:
in my purchase history, there is a message says We were unable to authorize your payment card for this purchase. Please update billing info. there is also a message like:
Amount you owe is 1.88 USD
Thanks!
