Debit card works for Apple Pay but not Apple ID

I’ve been using the same debit card for about two years with no problem. All of a sudden, I cannot renew in app subscriptions or make in app payments. I’ve tried to update my information but this message keeps appearing, saying it’s invalid in iTunes. I don’t have iTunes? I also don’t have another payment method at the moment. I’ve tried removing my debit card and re-adding it with no success. Is there a way to fix this?
