False prices marketed

My process for looking for air plain tickets is to go on to skyscanner or a similar comparison website and book the cheapest ticket I can find. So on the skyscanner and gotogate site a flight was advertised for 7090 Rand and only on the final page the price changed to 8010 Rand. There was no description as to why the price changed. My problem with this was that I would not have chosen gotogate in the first place if I knew what the actual rate was.
