I have tried calling them, but for some reason ticket they booked is 300$ more expensive then the one I found online. They just said, its cheaper online and is a bit expensive when they book themselves (When I already wasted 10$ on international call). Its a rip off. I wish there was a way to let them know there is the problem with their payment system or they are probable doing it on purpose so that they can charge more while booking with them. Super pissed!
