Kulula.com bad service..

I booked a ticket. The ticket that was mail to me but with the wrong flight time. I phoned immediately and they first want to charge me R400 to change, the when I asked to speak to a manager. After 30min holding I phoned again. Then the manager refuse to speak to me. But told the opperator to fix the problem. I was told that the new details was mailed to me.... It was, but the ticket is still wrong,. Nothing on the ticket changed All I wanted was a senior person to speak to me so I can get the problem sorted... I am still waiting..... This is the worst service I ever received from an airline.. It looks like I will need to go viral on facebook to get this sorted..
