Very frustrated Tax Payer

What a terrible experience altogether with SARS, from the beginning of submitting my personal tax return (26/07/2023) to today (20/09/2023). The auto-assessment SARS did on me showed that I owed them a rather huge amount of money, which was a bit of a shocker to me. I double checked what was done and picked up the problem. I submitted supporting documents as requested the first time in July 2023. I called to follow up in August 2023 and was told to upload supporting documents again, which I did, on 21 August 2023. I was informed it takes 21 working days. I waited. The 21 days lapsed and now I am being told that it takes 90 working days. The last person I spoke with now was very condescending if I may say. She is not able to share information on my profile because its inside information. I was told that her Manager will call me back, but she also didn't know when the call back happen.

I am absolutely frustrated, its really not like I want to loan money or anything. I simply want SARS to do what it should and handle my case accordingly. And yes, absolutely, if any money is due to me, I'd be too happy to get it round about now.

I cannot be told about 21 working days and then after waiting for 21 working days, I am all of a sudden told about 90 working days. No man.
