In case of available slot we issue the appointment otherwise we issue next date or time. 2- The scenario is about the detailed analysis of vehicle servicing and estimation of the cost. When a car is serviced and some new components are added in this scenario a customer service form is filled that elaborates the main components added and further services offered.
