The Shanghai Pudong Development Bank's installment display shows that the unissued deduction bill is to use the installment credit to deduct the amount of outstanding debt. This operation was unsuccessful. According to the inquiry of relevant public information, during the use of Shanghai Pudong Development Bank credit card, card swipe fees will accumulate, which can be used to partially owe money. If the bill has not been issued, it means that the deduction has not been successful, and the outstanding balance needs to be paid back in full.
