Can't Contact Roomate, Don't Know What She's Like

So I just found out that I won't be getting the single room of my dreams in college. Instead I have 22 year old roommate who all I know about is that her first initial is J, her last name is Harvey, and she's studying for animation. I really don't mind that, though, all I care about is that I literally know nothing about her. All the students took a survey and according to her and my answers, we both have about the same roommate ideals and want to be friends, but I have no way to contact her and can't find out anything more! She didn't provide an email or social media I could contact her through so I posted mine, but I'm pretty sure she hasn't checked and there isn't a notification system for our housing e-network. I just wanna know what kind of person she is and if there are any things we need to talk out, but I can't do that if the girl won't communicate😣😣😣
