deleting old payment cards from my account
How do I delete old payment cards on my account
Subscriptions, if you have those on your account, require at least one valid payment method at all times. Then it works best if you add a new payment method before you remove the old payment method(s).
If you have an unpaid balance, have subscriptions including an iCloud storage plan, or you use purchase sharing, you can't remove all payment methods. [1]
