Quality inspection is random sampling, listening to the telephone recording of the operator, and deducting points if any violation or wrong answer is found. This will affect the performance of the operator. Customer service needs to answer customers' questions by answering their phone calls and get customers' scores. The assessment content includes the customer's return visit rate and satisfaction. If the operator can't solve the problem in time, it is necessary to send a bill to the technical team and call back the customer within a certain time. In fact, every content of customer service will be included in the assessment, so the pressure is great.
