Obots, pity. I however will make case for Chisco as well as other transporters. Many travellers will confirm from you that what is nowadays called "night flight" is a mirage. The drivers are human beings who have families and will not wish to risk their lives transporting night crawlers. At a point last couple of years, the government had to ban night shuttles because of the unsafe nature of our roads (armed robbers, human (driver's) lethargy and pot holes) in order to preserve lives.
Next time you have an interview in a far distance, always plan to arrive early by travelling the day before during the day. Besides, the vehicles are man-made and even new ones can develop mechanical faults without prior notice.
Pity again about your bitter experience. A young traveller is wiser than the grey-haired non-traveller. I know you are wiser for it today.
