By any chance, did you request a chargeback from the credit card provider for either account?
When that occurs, public mobile denies the option to pay that account by credit card, and one must make payments onto the account by other means.
If this is not the case, try clearing cache and cookies, and using an incognito or private tab, to access the other account to update the card information.
Users also report greater success when doing from a laptop or desktop device, if available.
