Home affairs Capetown bad service

I have made a online booking for a new id document at home affairs in Capetown, appointment was scheduled for 11 -12 am , however I got the appointment early and only left the building after 2 the afternoon, the staff are in personal calls whilst helping client , two people go to lunch at a time , I don't know how they are conducting their service out there I will never go back there ... When I go and complain at the supervisor he just rudely brushes me off and had me wait my turn , this is supposed to be a straight forward service that is why they have the appointment system but I'm sorry I will never go back to that branch the service sucks !!!!
