Did Tong Yuan go out of business? Why can't I get manual customer service?

It has not been closed, so we can't contact Tong Yuan's manual customer service for the following reasons:

1. Busy customer service: During the rush hour, the customer service staff in Tong Yuan will be very busy and can't contact the manual customer service in time.

2. System failure: Tong Yuan's customer service system will fail, which makes it impossible to contact manual customer service.

3. Non-working hours: Tong Yuan customer service staff rest during non-working hours, so they can't contact manual customer service.
