why does my application request say "closed"?


I am a qualified intersen teacher from South Africa, this means I can teach from grade 4-9. I am also finishing my second year of teaching in december 2016, which means I will have 2 years experience before starting in Jan 2017 abroad. 

However after applying for January 2017 elementary post in Abu Dabhi, my application says closed. The lady that contacted me for my resume refuses to get back to me to explain whats the problem. 

Can someone please help me.
