Disrespectful and pure customer service

My reference number is ***, my name is Babalwa Mbedeni ID number ***. I was on a call with Sars for morethan 50 minutes with an agent for the income tax registration certificate to be emailed to me. The agent sent me multiple certificates under different customers details. I have the customers Names, ID number and address. I informed the agent regarding this and she got annoyed and irritated. She kept saying things like "I would not send someone else's details to you", "Why is the system doing that", "I don't know why it's doing that" she used those responses along the line with such an attitude. I informed the agent that I have been patient and on the phone with her for morethan 40 minutes and her response was "I have been on the phone with you for morethan 40 minutes as well", suggesting that she has a right to be aggressive and rude towards me. She finally sent the correct documents and put me on mute,not even hold but mute without even informing me. I kept saying "I received the documents", there was no answer. She came back after few minutes asking if I received the documents and told me she had to put me "on hold" to check the issue. I asked for her name and her exact response was "I gave you my name at the beginning of the call" she then left the call without saying anything and ended up hanging up after I waited for her name. She needs training on customer service, so that she doesn't do the same to other people. I would like the feedback to be sent to my email regarding this matter, email adress ***
