To the rep at Nintendo that listened to me and helped me unlink my NNID from a 3DS that I lost years ago. May 1,000 blessings fall upon your family for the joy you have brought to my joyless work-from-home days!

Posted about this a few days ago, but after calling in a couple of times and having to speak to different Representatives I was able to get a ticket escalated to unlink my Nintendo network ID from an old 3DS that I no longer have so I could relink it to a used new 3DS XL that I bought off of ebay. After a couple days of back and forth after the ticket was submitted, I was able to recover my account and download my games again.

To the person that helped me, you are amazing. I hope everything in life goes well for you. Thank you for listening and helping.

Good luck to anyone else trying to get their Nintendo network ID link. I see that it's a pain in the butt now and I got very lucky. Keep trying and I hope you get it!
