At least with a human you have a way to make your case or ask to speak to a manager. Of course they could deny you, but in my experience it is rare to be denied if you persist in politely asking.

Without a human to contact, you have no recourse. The email that you received denying your request for re-evaluation is no-reply@big.co, so you're stuck. It is a surprisingly awful feeling of helplessness. In fact, if a human on the other end of the phone were to say, "I'm sorry, it doesn't say why, but our system won't let you back in.", you would probably feel a little better because some soul heard you.
