Create a system sequence diagram that illustrates the process of returning a vehicle

Return a vehicle: Customers must return their vehicle by the date and time specified in their rental agreement. Once returned, the vehicle is inspected by a technician for damage and fuel condition. The technician also records the current vehicle's mileage on the system. If the fuel tank of the vehicle is not full, the technical will need to drive the vehicle to the petro station near the office to refuel. The customer will be billed for the cost to the fuel plus a refuel service fee of $50. . .If there is any damage and the rental agreement includes a zero-free excess reduction option, the customer is not liable for the damage. Otherwise, the customer will be billed for the excess fee. After the inspection is satisfied, the technician updates the status of the rental agreement to "completed" and also updates the availability status of the vehicle (i.e., from unavailable to available)
