DATA BASE SYSTEM

Good Day I would like to know if anyone can explain to me why my name was not taken from the data base yet.seems everyone I asked can not explain to me why..yet I am on there for years and not one's has my name been chosen .not even for entry level clerk work..yet I see how younger people are getting work for clerks and I am 31 already waiting for years...how is it that my name is being looked over for entry level permanent post?for years now.what is the reason for this?and I am being told in due course? Seriously
