Once the order has been validated, it is no longer possible to change the payment method. If the passenger has ordered in cash, but has run out of change, simply advise him to go to an ATM so that he can withdraw the amount of the journey :) Conversely, if the passenger has chosen the CB payment method, cash should not be accepted. If the passenger has been able to order by credit card, it means that he has one on his profile and we will take care of debiting it.
