Worst call centre I've experienced in a while

I booked a return flight from Cape Town to New York on Air France/KLM via Amsterdam and found out by coincidence that, because the airline transfers me from Paris to Amsterdam on the way back to Cape Town, I need a Schengen visa even though I am in transit and not entering the country. This adds another R1000 + to the price of the flight and in my mind this boils down to misrepresentation as I could have booked a flight via London or Dubai for the same price without paying the visa costs. While doing the booking, there was no indication that being in transit in two European countries requires a visa. The call centre people were totally uninterested in my predicament with standard call centre answers such as \we take no responsibility for online booking"and \""we know nothing about visas\"". Even the Fly Blue call centre"
