Worst service ever

My appointment was booked for 9h10, got there at 7h45 and was made to stand on a queue for 2 hours before being assisted. Took pictures and then waited again for 3 hours for the cashier to assist with payment. The booking system is not relevant, the staff issue out tickets to their friends using back doors, the guy who was behind me got a ticket that was 14 times behind mine. Only when you get to the counters where they ask for confirmation but security guard is never concerned who booked and who didn't. The queues went outside the gate however only 2 personnel and 2 cashiers were assisting at the counters.
