DNA on Nike is pretty easy, I have had always good success, though remember that if you get the annoying rep who wants to start an investigation first say that you need the replacement/refund fast and stuff, if it still doesn't work, refuse and say you'll look in the matter yourself and you should be able to retry till you success.
If they start the investigation you can always cancel saying your mom/family hid it, but I wouldn't suggest to try DNA'ing again after cancelled investigation as you've stated you had the package, either let the investigation go or try to ftid v3 them
