Failed booking on Kulula.com and they want nothing to do with it!

Just made a booking on the Kulula.com website for an international flight with British Airways. The booking hung during the payment process so I have had my credit card billed but my booking has not been made. When I called Kulula.com their help desk said that they cannot assist me because the I book a British Airways flight. They said I needed to contact BA to find out about they booking because Kulula have nothing to do with the booking!

So I called BA and after immediately trying to be palmed off to Discovery (they provide discounted flights on Kulula) the helpdesk confirmed my fears by saying that the flight had not been booked and although I had been charged, they could do nothing about it!!! They said I need to contact Kulula or Discovery!

I am really confused because I made the booking on Kulula's website, I received a billing SMS to say they Kulula had billed me for the flight, I should have received booking confirmation from Kulula so how on earth can Kulula say they have nothing to do with the transaction?
