FlightNetwork Hidden Costs not Disclosed

South Africans, and potentially anyone else not booking from Canada or US, please be careful. All currency exchange fees and other charges are not disclosed when booking the flight. I used skyscanner to search for a local flight, selected the flightnetwork price as it was the cheapest, and finalised booking. When adding my card, and requesting final payment it gave me a Visa card fee associated with the transaction. One does not normally pay a Visa or mastercard fee when your card is debited for payments. I went along with this, but this card fee was 12% of the total booking cost which is a fair amount. I should have gone back and checked immediately why this was being charged, essentially I paid more for the flight with this fee, so in the end flightnetwork was not the cheapest option presented. Then lo behold, about 3 days later, I see an international fee cost on my bank statement, and upon researching realised this was a Canadian company and not a local provider. Only select local and compare the prices. Flightnetwork did not disclose the currency conversion cost that you will pay, this automatically debits off your bank account a few days later so they do not include this in the flight cost. All in all, it ended up with flightnetwork being the more expesive option to book.
