self-reported as a new customer service, telling customers that the former person in charge left his job can be said to be due to some personal reasons, such as (going home, taking a long vacation, or getting married), so that customers will understand, and then introduce yourself to the customer in detail, so that he can remember you, and it is ok to contact you directly if there are any problems and needs in the future. Remind the other party before hanging up, and save your contact information if it is convenient.
