I have nothing new to say. I, like many other people, paid for my tickets and the next day the prices were raised and they asked me to pay the difference or they won't book anything. It works when you urgently need to book tickets. Using tactics like this is unethical. It only shows how much you disrespect your customers. plus, they have a bunch of hidden and additional feel they will never tell you about until the moment of payment. So you decide whether you want this mess in your life or not, but I would stay away.
