ticket not booked!!!!!!!!!!!!!!!!

<p>I did an online booking with kulula on the 26th of october.I received an email from them saying its paid and got a booking code.I also received an sms from my bank to say the transaction has been reserved.I did 2 bookings at the same time and received the same sms for both so took it as granted that the payment had been done as i recieved confirmtion from kulula that both were paid with booking codes.Now when i tried checking the booking it says its not valid.When i contacted kulula.com they said that they will check and get back to me.Which they did 1 day later.Then they said that the money had not gone off from my account which i had not checked so the booking is not valid even though they sent me proof it is paid!!! now they say I must pay the full rate for the booking !! I only booked the holiday because the flight was cheaper!! Cant belive they refuse to take reponsibilty for there system messup and now i must pay for it!!</p>
