SPEND TIME GOING THROUGH THE BOOKING PROCESS AND .. SORRY THERE WAS A PROBLEM - TWICE!!!

Went through the whole process of booking flights and car. I got a message "Sorry, there was a problem with your booking. You have not been charged. (yeah right!!). The following errors occured. Your selected itinerary is no longer available at the displayed price, or one or more flights may have sold out. Please restart your booking process, or call..." Fair enough, so I am about to restart the process and I get an sms that I HAVE been billed TWICE!!! Call the call centre.. very efficient lady tells me "no problem" we will credit your account within 30 minutes, which is duly done! Cool! Mistakes happen. Start the process again...... You guessed it same result, although this time I am only billed once??. Same message. Call the call centre get told "it may take 24 hours to credit" REALLY?? I told her the other lady did it in 30 minutes, she speaks to me as if I am retarded. I am sooo irritated I put the phone down! Let's see what happens with the credit. What a pity, (used to) love Kalula!! Never had a problem booking online before. Will give them 3 stars for now, should be 5
