After sending a voicemail to Kristy Myrick, Senior Director of Guest Assistance and Customer Care, a nice lady from corporate called me back and apologized profusely. She is going to look into what happened by first calling the GM of the hotel and then the GM of Hilton Loss Prevention. As always, I will keep this thread informed. I also encouraged her to persuade Hilton to issue a formal rule or standard on when an account can be closed, and the process behind that closure. She is going to look into that.
