Well, I at least got someone from customer service to acknowledge there was an issue. I believe the trick was using publicly available web pages to make my point and trying to explain the difference between the system they're seeing and the user interface.

Hi [---],
Good to hear back from you, I hope you're well today.
I'm sorry to hear that you've been unable to download the latest episode of "Fringe, Season 4". I know how eager you must be to have this matter resolved, and I would be happy to look into this for you today.
Apple is currently working toward a resolution for the issue you have reported, so I had no intention on refunding your SeasonPass unless you had specifically requested that resolution. You will receive an email after the matter has been investigated and further information is available.
Thank you for your patience, [---]. Apple wants your iTunes experience to be as enjoyable as possible. Take care, I hope you have a lovely day!
Sincerely,
[---]
iTunes Store/Mac App Store Customer Support
Please Note: This week I work Mon- Thurs, Sat 7:00-3:30 PM. Thank you for allowing me the opportunity to assist you.
Okay, first of all I want to keep my season pass. I don't want it cancelled. I want to keep my subscription whether or not I'm able to download this episode. There are people in the user reviews saying that you'll cancel our subscriptions if we keep complaining about these kinds of things, that's why I was hesitant to respond to your response.
No I wasn't able to download the episode. iTunes thinks that I have a download queued. But it refuses to download. I believe that's why your system is saying that it's credited to my account and ready to download. This really seems to be an issue with the system you're looking at communicating with the user interface, leaving me, and everyone in the most recent user reviews unable to download the most current episode.
Here's publicly available pages to communicate what's wrong.
http://itunes.apple.com/us/tv-season/fringe-season-4/id457183481
It goes from 15 "A Short Story About Love" to 101 "Meet the Cast of Fringe" which is a special feature.
Wikipedia to prove an episode 16 "Nothing As it Seems" exists and aired.

Finally, the most recent user reviews are filled with complaints about this very issue, without anyone saying they were able to download the episode.
