SARS PATHETIC TO FINALIZE AUDIT 2023

Every year I am put under SARS audit. Then we update all documents and wait for the turn around time. This year 2023 audit year , SARS had there 21 audit days but now after escalating this matter 8 days after there 21 days , they say its not done yet and i have to wait another 90 days due to manual audit. How does this work. Paid the penalties and all. Now they keep on saying im under manual audit. This a really bad and pathetic service from SARS. How to i take this matter futher.
