Waiting 1 year and 6 months for proof of name change

I app**** for proof of name change on the 31st of May 2022 and was told it would take Up to 6 months, mind you, I did not apply to change my name, this was already done, I just wanted the proof that it's been change. After the 6 month mark I started calling and there was never anyone available. I got hold of someone one time and she gave me and email address to send all my info, which I did, she responded a few times and then stopped. I kept calling and emailing many times but no answer. Then I spoke to a few people at a different home affairs and they told me there's no way that it should take this long and that I should go to the HA where I app****, and speak directly to a supervisor. So I went to Bellville branch in September 2023 and explained to employees why I was there and they directed me to the supervisor without me even asking. I waited and waited while the supervisor proceeded to have casual chats the some of the employees. When he came out of his office I approached him and he just looked at me and carried on walking, so I waited some more. He came back with a different employee and went straight to his office again, not even acknowledging me, they sat there and chatted and laughed and had a good time while me and other people from the public waited to see him. As time went on more and employees joined in. Eventually they left one by one and when they were all out of the office the supervisor just sat in his office not even calling any of us to come to his office. I then asked one of the employees if the supervisor is still busy as we are all waiting to see him, she told me that I can go into the office as his not busy, which I did. Immediately when I walked into the office this man was so rude. I started telling him why I was there and he just kept messing in my mouth. He was so rude. Then another employee walked in and the supervisor told him that we want to jump the line and the employee said to him "I saw them sitting here, they know exactly which line they suppose to wait at, they musnt act stupid". I really had to keep my composure. I then again tried to explain why I was there and that I was directed to the supervisor and that If i knew I'm suppose to stand in a certain line then I would not have wasted me time to wait here for over an hour for the supervisor. The employee again said I mustn't act dumb and before I could respond they both put me out of the office, my husband was with me and recovering from a car accident so he just had to be quiet because he cannot stress. They shouted at me to get out of the office and not come back then the employee pointed across the room and said go sit there, I wasn't clear where he was pointing to so I asked him where are you pointing he told me not to be stupid and walked away. I ended up sitting in a line which I thought he pointed at since he did not want to show me again. I waited for another 45 mins in the line and eventually ended up at this same rude employee. He asked for my ID, went onto the system and said "sorry its not ready" I told him that I was told it will take Up to 6 months and he said these things can take many years and I must just wait. To avoid losing my cool, I took my ID and left. Mind you, this employee was so rude to everyone, you could hear different people complaining and arguing in different sections of the room. When I got home I emailed HA about my experience and they said that will expedite my case and that I should contact them in 2 weeks. 2 weeks later I emailed, and I got the same response that I should contact them in 2 weeks. This went on for a few weeks and then the replies just stopped and now I'm not getting a response from anyone. I really don't know what to do anymore because I really need that proof of name change.
