Inefficiency at SARS

I used to think SARS gives the most efficient service but I was wrong. I have been dealing with a matter since Jan 2023,paid my late dad’s penalty that kept increasing monthly. After paying I was told there is another penalty,to top it off I was asked for IRP5 and medical certificate from 2015/2016 years after his retirement and 2 years after his death. Anyway, I respect SARS so I had to go beg for those documents, uploaded online more than twice, submitted physically at the branch twice and I have been asked to upload online again. I remember accompanying my dad at SARS in 2018 and we were told there will be no need to file because he last worked in 2015. I am angry,disappointed and sad that SARS is inefficient even to a person who died 2 years ago.
