Student Accomodation is a huge problem at Kingston.
I'm a first year in halls.
I got rejected for halls (despite being in specific criteria of over 19 miles or something) at first.
I remember loads of people did.
People from Manchester to even Ireland didn't get halls.
If you do get rejected, ring up, and if they tell you no, ask to be placed on the waiting list.
Emailing them is a waste of time, they just send you emails on private housing and stuff.
I managed to get a room, on the day on enrollment.
Literally, while waiting in the queue, they gave me a ring on my phone and said they had a room available.
Crazy stuff.
