Cancellation of Saudi Arabia Iqama?

I came from Saudi Arabia in December on final exit, but my iqama is still showing valid upto//, meaning upto Aug-. My previous employer provided me documents showing  Final exit (Kahrooj Nihai), but Saudi Embassy is objecting that iqama is still valid and ask your employer to cancel it. Please guide me how can i get confirmation of cancellation of my iqama.
