It means that your cross-boundary coach ticket refund application has not been submitted successfully. You can check if the ticket has been used first, if you have submitted a refund application repeatedly or if the application was submitted more than 90 days after the original departure date. If none of the above situations applies, please try to submit your refund again later through our WeChat mini programme or submit the cross-boundary coach ticket refund form on our website. If it still displays “Fail to refund”, please report the error code displayed by the system and contact Customer Care (400 815 2888).
