Contact a SanDisk Support person… and Include a screen capture of the refusal…
I just had same thing hppen to me… It was an exchange SSD unit…
I contacted the support engineer I was working with, and included a screen capture so he knew what model and serial I was trying to register…
And he did the reistration for me, and I got an email thanking me for tegistering the product…
So I know that will work, because I had to do it too!!!
Good Luck
