Intui, as well as the Transport company, can not guarantee the fulfillment of any requirement and of any change. As a rule, because of good reasons, the Transport company has the right to decline made changes. If the Transport company declines the order changes you made, you have the right to let your booking remain as “it initially was» or to cancel your order. In this case, the conditions of the order cancellation remain valid including the refund of the whole paid sum.
