Voyager miles online booking not working

<p>I have been trying to book a ticket using Voyager miles for weeks, but the site remains broken.</p> <p>I was informed that if I book telephonically, I will pay R100 extra (besides the airtime use) and R200 extra if I book at an airport. Can you please advice on how I can book my flight online and not face the extra charges and the time it takes to book a ticket telephonically?</p>
