4/25 Update: Apparently, it was an "error"

I got the following email, indicating that the bill I received was a mistake. Apparently, they generated said "error" when "ensur[ing] everything had been closed out correctly." How ironic. Even more ironic is that the "error" is actually a portion of my legitimate final bill. However, given the earlier discussions that my final bill was $0.00, I am not fighting that battle anymore. The money was sent to charity.

So maybe this is the end again. I sent a follow-up on the explanation I want so much, but I don't think it's on its way. No big deal. I will just pass along a copy of this blog as an FYI to corporate when I get back from vacation. That's closure for me.
