When a booking is almost finished before making payment, use may click and come into stripe page. At that time use may need to input credit card info. However if the credit info is not available and user want to go back to last step. The order will be cancelled straight away.
The common process when use come back from the payment processor, the order status should be still in pending for payment, which is common for e-commerce website.
How the development team can improve this.
