Hello My name is Anutsara from Kore

Hello My name is Anutsara from KoreanStudies, Chulalongkorn University, Thailand.
We did check Accepted wait-listed students for fall semester for Dormitory.
But we don't get the room( our number is not in annoucement) This is also happened to my friends too, except only one person in our group(Ms. Ratfah Laosuwanwat, SNU ID 2013-82173, Waiting list no.22).
