No, However 99% of times you will get the vehicle you booked. If we do not have the vehicle you booked due to unforeseen circumstances, We will try our best to place you in a better more costly vehicle. In the event you are transported in a vehicle which costs less than the one you booked, We will credit you the difference in fare. In case of a more costly vehicle substitute, We will not issue any refunds or offer any discounts.
