Either the ticket may not be authentic, or the ticket money has not been received correctly (at this time, the ticket office may cancel the reservation, and if the ticket has been issued, the refund will be returned)
Suggestion:
You can only call the customer service center of your airline.
Confirm whether the air ticket reservation is successful.
1. If you are sure that the ticket has been paid in full and the airline confirms that the ticket has been issued, you can successfully board the plane.
2. If your ticket cannot be booked or refunded, please contact the place where you bought the ticket for consultation. Of course, you can also find other places to buy tickets.
