According to your description, it is not overdue, so if the landlord wants to know his consumption bill this month, he can inquire in the following ways:

First, CCB's credit card bill can be queried through WeChat. The specific way is to pay attention to the official WeChat account of China Construction Bank's WeChat search, and add a bound credit card before querying.

Secondly, the landlord can also go to CCB official website to make an inquiry, select "Credit Card Inquiry" in the "Account Inquiry Service" on the left side of the webpage, and after entering the information as required, he can inquire about the details of the last six months in CCB official website.

Third, or the landlord can inquire through CCB customer service telephone, follow the prompts to enter the telephone voice system, and then transfer to manual customer service to audit the accounts.

The above is the information I have learned. I wonder if the landlord understands. I hope my answer can help the landlord!
