I finally received my first decent response from Amazon Payment Customer Support:
Amazon.com Customer Service to me
Hello again from Amazon Payments.
I apologize for our misunderstanding and delay in responding to your message.
We do have the ability to review your previous correspondence with us, and I see that you were notified April 25 that your account had been reinstated.
It appears that my colleague misunderstood your concern, and instead of recognizing your desire to simply have the account reinstated, he was checking into the specific transaction you were wanting to make. I'm sorry for the mix-up.
I'll also pass on your feedback concerning offering phone support.
Thank you for using Amazon Payments.

Thank you JoEllen M, for providing the very first email from Amazon Payment Customer Support that sounded like it was written by someone who had read the case history, and who was willing to take the time to write a non-form-letter reponse. If this had been done last week (or back in Oct/Nov when it first happened) you would have saved me and Amazon a lot of time (and bad blog-press).
