While noticing Kulula's new Southern African destinations, I noticed Kulula's web site got updated. Of course, it's utterly broken, and won't render useful things like your itinerary and price. Also, their day of departure/return makes finding out whether there are flights on the once a day but not every day routes (such as Windhoek) really hard.
My uncle pitched at the airport for a flight to Durban on Kulula, supposedly at 7pm, a couple weeks ago, only to be told that the flight was actually at 7am the next day, and that the website was wrong. That's completely insane.
