unexplainable price increases.

Just tried to make a booking as I am confirming everything it tells me that price is no longer available (for no reason) came back an hour later with the new ripoff price put in all my details clicked pay then it says flight no longer available so did it all again only to find the exact same flights for an extra $60 (once again for no reason!.....other than pure greed!) completely evil and stupid company I hate them so much! and I never leave reviews for anything even if a restaurant serves me cold food. I am the Queensland Chess Champion and think this airline is one of the worst moves anyone can make! there is only one company on planet earth that is worse than this one.
