Sars have rude people working at their branches

Went into the branch last week after waiting for a week for a appointment and the lady there was very rude and did not explain anything and simply said she did a dispute and I must wait for it to be sorted out and when I asked if payment arrangement can be made for the money that was owing for 2020 she said dont worry about it as she put a dispute and I told her that I am getting letters of demand for that money she said for worry about the letters..so they send me another final demand letter and the lady I call at the call centre tells me no dispute is done on the system so I go back to the branch and after some pleading am allowed in to be helped by another rude lady who was not interested in what I was telling her and didnt even want to check my phone as I wanted to show her the problem..she said i don't need to see all that..so I left there again in the same position i was in due to these rude people who helped with nothing and told me nothing.
