Been takin from pillar to post by SARS argents

Poor service received at SARS from the call center agents,

I wanted to change my banking details of which they advised me to do so which was going to take 21 working days, First attempt I uploaded my details on 22 July 2024 and and I called in the next day, the consultant asked me to delete my upload and manually enter my details on SARS registered details of which did not work because they asked me to re upload on 26 July and I did, second attempt, I uploaded on 26 July 2024 and yesterday a consultant asked to to add a selfie with a clear drivers license which was not requested via e filling so I did, and now I found out today that I shouldn't have because I have lost out on my 21 working days that I have already waited which was supposed to end this week Friday 23 Aug 2024, now I have to count another 21 working days.

The call center agents have waisted my time numerously, why should I wait for 2 months to get simple banking details updated on SARS system??? Not happy with SARS System.
