I set the pre-authorized payment on debit card before and the statement shows me the date of pre-authorized payment, but the bill wasn't paid when it is due. Whether I miss something? Additionally, is that OK if I pay the bill after due?
It takes 1 full billing cycle for the pre-authorized payments to kick in from your bank account. So the month that is owed has to be payed manually through credit card,online banking or bank teller. At which point, the month after the payments will be taken from your account on the due date.
