Help! Can’t use the Kindle I bought from Woot

I bought a used Kindle from Woot! It arrived fine, good condition. But… I can’t use it. There is no way to unlock the Kindle. When I tried to register it to my Amazon account it said “Reported Lost or Stolen”. I called Woot! & they knew this was the case. They said ALL resells are “Reported…” & they can’t unlock it, only Amazon can. I contacted Amazon & they said, “No, Woot! needs to handle it because they sold it.” So here I sit with an unusable Kindle. Woot! offered to exchange it, but then said they didn’t have the product anymore. HELP!!! and thank you.

PS I don’t even know HOW this a problem, since Woot! is a subsidiary of Amazon…
