Recently, CCB's customer service is a bit difficult to call, but I can get through. I just called the other day and waited for a long time. I waited for the first automatic hang-up, and then called again. I waited about three or four minutes before switching to the manual service.

Many businesses don't need to be handled manually. I can't change the information, so I have to, because I have to. Usually, I do my own business through online banking, such as auditing accounts, purchasing foreign exchange, checking points, applying for installment, billing installment, changing email address, changing mailing methods, etc ... quite a few businesses can be handled by myself.

See if you can do the business you want. If you can, you don't have to do it by hand.
