"Unsettled payment” is displayed and cannot request a car

Please select the relevant history from [Usage History / Receipt], enter valid credit card information, and complete the payment.
If the unsettled payment is not cleared, you will not be able to request a car using GO Pay.

If payment is not made within one month, GO may contact you by phone.

Please note that even if there is an unsettled payment, you can still request a car by selecting in-car payment.

If you have any questions, please contact us from [Menu] tab > [Inquiries] in the application.
