I called the housing department every fifteen minutes starting at 9am this morning because I remember hearing on someone's answering machines that they're in the office from 9am to 6pm. But that might not have been this specific person I'm looking for.
I got caught up in the internet and by 10am, I forgot to keep up my diligence. I didn't get a call from the HD like I expected. The paperwork lady (I forgot her official title) called to let me know that everything was submitted okay. But she's just now getting back to me when I called her a week ago.
She transferred me to the person in the HD that I've been trying to get in touch with. I'm not into staying at the hostel, so she's get two other possibilities for me. But I still don't know because I'll get a call "by the end of the day to confirm."
I now know that that is just a way to get you to not bother them all day and they have the possibility to return your call till the next day if they've slipped out of the office by the time you've called back.
