I haven't reached the stage of manual service, and I don't call during office hours. Even government departments have working hours and off-duty hours, so it is impossible to make a direct phone call. Therefore, there is no manual customer service until the manual service stage, and there is no manual customer service during working hours. In the customer service hotline, there is only manual service during working hours during the day, and messages are recorded from 5: 30 pm to 8: 00 the next day. Weekend is a rest day, and work is not online.
