SARS DILLY DALLYING WITH MY TAX REFUND - " LIFTING OF SPECIAL STOPPER" DECOY

Since July last year (2020), I received information that I was due a significant amount of money in the form of a refund from SARS. First they asked me to update my account details, I did so by submitting documents via the correspondence system on eFilling. They said there would be an outcome in 21 working days. That passed and nothing happened. I called to follow up and they said that the money was not being released because of a 'lifting of a special stopper', so I set up an appointment and the only available time was 31 December. SARS called and they said I had to resubmit outstanding documents via the Sars.co.za platform (this was the second time). I had initially changed my banking details via the APP, the APP allows a user to change their details. The SARS employee who called me on the 31st was not aware of this and said this is not a possibility, though this is an actual thing. I get a call then on 6 January from the same SARS employee saying they received my documents but now I need to submit a proof of payment to SARS. There is always something that comes up that they make sure they use to stop you from getting your money back. If it is not this it is that. What is going on at SARS?! Is this ********ity? Because I can see some other people here are having delays with their due refunds too.
