No you can’t. Because merchants need the payment to confirm the order. This is a protective measure for the merchant to prevent from arranging a service for you but you do not show up to cause losses in the end. If you have booked the Service and paid for it, but you change the service item or increase the service scope during the actual service on the day, you need to pay the merchant for the additional service fee. In this case, you can pay the merchant on-site. Alternatively, you can also pay through the platform by ordering the "$1 products" to pay the additional fee to the merchant.
