"Contacting Admissions by phone"

I have spent over 3 hours trying to contact the admissions dept by phone on 5 different numbers I have been given. The lines ring incessantly and then cut out. How is one to find out what is going on when access to speak to so one is so unavailable? The various staff I have spoken to in order to get these numbers, have been helpful but the end result is very unhelpful and frustrating. Do I need to actually visit and find the admissions office to get any response? I was told I would be listed as an urgent case but need to know how this bears out in practice with current waiting lists.
