Why is the credit card customer service of ABC always busy?

First, the time period is not selected correctly. On the billing day, two days before and after the due repayment date, Monday to Friday, there are more customers calling in the morning and afternoon, especially at 5- 12 in the afternoon.

Second, make more customer calls and less customer service calls. The treatment inspection and system are not perfect, resulting in less customer service staff and long telephone calls. In addition, because most card issuers of ABC don't know much about credit cards, they are not good at using self-service voice services, and there are too many manual services and long phone calls.
