I've been continuing to work with Cederic, as mine hasn't had a status change since the 22nd of September. He expressed frustration as well, because they reached out to the Dutch Post for a status and were met with the same stonewalling. They provided me an extra game key to play the game as an apology while I wait. My best recommendation is to keep hitting up their support e-mail and to give them every little detail you can find about any investigative work you've done.
If you know someone who know's German, blow the Dutch Post up with phone calls because those fuckers have royally dropped the ball and don't give two shits at this stage.
