2018/04/20 - You can re-try your payment in "My Page"
As our payment system has been changed to the transition type for security reason, your "Purchase" and "Payment" become different phases.
It means your order could be completed WITHOUT payment.
Please make sure your payment being already made or not, heading to "My Page",
where also you can re-try Payment in case of incomplete payment.
Thank you for your understanding.
