Overcharging on Internet payment

I purchased a ticket from Johannesburg to Auckland., I searched [URL Removed] and then was directed to Bravofly. The ticket price was R16420,00 when I paid for this on my credit card I was charged R17600, 00, and additional R12000,00. <br> <br> I have been unable to contact Bravofly as their contact number was unable to be reached. There is no indication in their terms and conditions that this would occur and no explanation can be found. <br> <br> I have filed a dispute complaint with my credit company.
