Every month, the debit of ants is 19. Why didn't you deduct it this month? There is a balance on the bank card.
Ant IOUs automatically deduct money from balance, balance treasure and binding bank in turn, but actually only automatically deduct money from balance and balance treasure on the day of deduction. Even if the deduction is not enough, money will not be deducted from the bank card you are bound to. It will only send a message to remind you, so you still need to take the initiative to return it.
