To be fair, in my case, I did not. I actually received one as a gift last Christmas. I never got around to setting it up (still in packaging). I was planning on trying it out when I had some free time. Now I have a useless device that I can’t even return since I refuse to create a Facebook account.
Return it to Amazon.
You can use it for at least two years if you create an oculus account before October, according to the linked statement.
