1. If there is no money in the debit card and it has exceeded 1 year, the bank will automatically cancel the account for you. If there is cash in it, take your ID card and card to the bank counter to cancel your account. 2. If the credit card has no arrears and balance, you can punch in the customer service phone on the back of the bank to cancel the account (officially cancel the account after 45 days). If there is debt in it, go to the bank counter to pay off the debt. Not bad, and then call credit card customer service to cancel the account. If there is a balance in it, open the pre-sale account first and return the credit balance to the bank counter 45 days later. Your debit card that is not a debit card is not expected to be mailed, so you can only go to the bank counter to handle it. You are processing a credit card.
