Those are GR. There are a lot on Ebay. They are the Flyknit Roshe Neo Turq. They were released several months ago, and NDC did a restock maybe a month ago, but haven't seen any online since.
You can send them in to Nike and get a voucher for retail value that can be used on NDC if they determine it is a manufacturer defect. Don't need receipt or anything. They go by the manufactured date on the size tag and if you are within 2 years. Sounds like this would qualify I think?
Code did not work for me either. I did Live Chat with them, and they told me they could not apply because I had used another bday code within the last year. YMMV
Could get them for ~$70 + tax if you go through Discover portal, use Summersteal coupon code, and call in to have them add WC reward (I just did that, and it works. They will refund the $20 once the shoes ship)
