I contacted Nintendo because of my problem with my NNID and they said the can't change it and also can't do anything about it.... >_<
Man that sucks! Either i lose a lot of digital games or i can't use Miiverse anymore. 
If you're interested in Nintendo content and understand german, maybe you want to take a look at my youtube channel! :)
