What if I’m downloading a game I want back

If you are being asked to enter a payment method, Apple has multiple criteria* requiring the presence of a payment method, even for free items. Since you may be encountering one of those situations, you have no option but to enter a valid payment method if you wish to continue downloading. Read the support article Add a payment method to your Apple ID - Apple Support about how to do that. The payment method may not be charged if you also have account balance or the item is free, but the payment method has to be present. This next article lists valid payment methods for different countries but note that in this situation Apple Account balance alone apparently may not meet the requirement and you need to use another payment method until you find one that satisfies Apple's requirement (often a credit or debit card): Payment methods that you can use with your Apple ID - Apple Support .

If you have already entered a payment method, use the first link above to check it. If a message appears in red there is a problem with it. If the information is still correct and current, contact your financial institution.
