Ugghh I just called the housing office and was told basically "oops." They said it's too late to assign me a lottery number now. And the phone person told me to send an e-mail to hlsdorms to ask for help. Always a sign of incompetence when an e-mail tells you to call or a phone agent tells you to e-mail.
Bleh, that's horrible yc. Hopefully you can work something out.
