Update: Marcus is on the case; contact him (and read your UiO e-mail!)

Marcus and myself had an improvised meeting with the Department's administrative resources right now.

• You can contact him on the matter, and
• the Department has agreed to forward communication from him, most likely early next week - thus, keep an eye on the inbox of your UiO e-mail (the one that the University uses in formal communication, e.g. "student.*.uio.no" type). 

Edit: his e-mail is marcusbr@student.sv.uio.no
