After I had technical issues I resorted to having to use a backup. I had the backup before I updated so nintendo didn't ban my system at that time. When I used my system I found everything working and quickly turned off the send data to nintendo thing in my internet settings and show if friends are online on friends. I checked if I could go onto my eshop, internet, badge arcade etc. and everything was working. Other than the ban notice glitch on my friends whenever I go onto the application, everything was working. I wanted to tell you guys if this can actually fix the ban or if its just my console being weird which technically shouldn't because nintendo banned my NNID... If you have a backup and wouldn't mind trying you should probably try this, not confirmed if it works though... or i'm just stupid...
