No, I was never able to contact a live person at Amazon.
However thanks to this Hacker News article, three Amazon employees have contacted me, with varying degrees of success.
As of this moment (around 4PM Pacific time on Wednesday30 June), my listing has been 404'd ... I'm unsure if I will be able to recover the reviews if I rebuild it. Or even if I can rebuild it.
Most of all - thank you to my friends on HN. What a bright spot in an otherwise weird situation!
