I was able to take out a subscription using a prepaid credit card. However my subscription auto renewed and it resulted in outstanding subscription fees. Upon accessing my purchase history, it tells me “billing problem”.
Bottom line, I was not told that I required a real credit card, debit card or PayPal prior to obtaining my Apple iPhone account. So my only means of payment is either a prepaid credit card or my Apple balance amount which has enough to pay off my outstanding subscription fees.
So seeing that I am not required under contract with Apple to be in possession of a real credit card, debit card or PayPal, and there is some sort of Apple bug preventing my Apple balance funds from being used to settle my debt, the issue is on Apple, not on me. It’s their bug, not mine. If they won’t allow me to pay, then it’s out of my hands.
