Generally, I receive a repayment message, reminding the landlord that the card is in arrears and needs to be returned. If the landlord has not used a credit card during this period, it is suggested that the landlord can check the bill details of CCB credit card and confirm the source of the arrears.

The specific method is shown as follows: (Enter the official website-Left Account Inquiry Service of CCB, select "Credit Card Inquiry", and enter the information as required to inquire the details of the last six months. )

If there is still no way to confirm the details, or the credit card transaction is not impressive, it is suggested that the landlord can call the service hotline of CCB to ask, and the customer service can give you detailed answers or assist you in further inquiry and confirmation.
