Starting to hate this ticket more and more.
So I called the RTW desk again, with my problem, and she didn't feel like looking into it, but said my PNR was fine. She transferred me to web. There they said they couldn't do anything because it was something international (also said the PNR was fine), so they transferred me to the international res department (or something like that). The rep put me on hold for 25 minutes, while talking to a supervisor, but then my connection dropped.
So I called again, another girl contacted her supervisor again and after 15 minutes she told me the website is having technical difficulties, and the problem should be solved somewhere in the future...
Like she needed to be talking to her supervisor for 15 minutes (and the other one for 25) only to come up with that explanation... They just don't know what's wrong.

For a 9000 USD ticket (2x4.500), you'd at least expect them to get things working the way it's supposed to work...
