Bad service - SARS offices in Nelspruit

I visited the offices of SARS Nelspruit today, at 7:30 in the morning I was waiting in a queue outside the building. They open the doors and everyone went in. I got a ticket number 100 for Small Business and was directed to a certain department to wait for my ticket to be called. Staff members are doing ups and downs but not assisting clients. They started disappearing and when I ask, being told is lunch time. It is now 14:06 still waiting for my ticket to be called. I don't want to sound ****** but I want to share with you that whites comes in and out in less than 30 minutes waiting being called with their tickets 236, but I came in the morning and not being serviced. Dispute the fact that my query is different from theirs, the service is very bad. I feel the staff members are missing a point, service is key and what is happening at the offices of Sars Nelspruit is a chaos. Is that branch having a Manager? Is it because we are black. I will be sending pictures to show you the chaos in the offices. I need the Manager to call me so that I express my concern and guidance on rendering excellent service. My number ********** 475.
