It is possible that the landlord's credit card is still under review. Generally speaking, it takes ten to fifteen days to review credit cards. If the time to submit the application is not long, it is recommended to wait patiently. If the landlord submits the application for more than one month, it may be that the landlord's application for card opening has not passed the bank's audit. Specifically, the landlord needs to call the customer service hotline of the card bank for consultation. This is the information I know. I hope my answer can help the landlord!
