Hello, account cancellation does not affect personal credit information. If China Merchants Bank uses a credit card to cancel the account, please call the credit card customer service hotline (the back of the card) after the credit card account is settled, enter your ID number or card number and inquiry password according to the voice prompt, and then select the "9" transfer service specialist to cancel the account for you. Cancellation is free, and it is not possible to cancel the account through the network at present.
