Unavailable service at sars

I received messages to change my bank details. I tried e-Filing: "you don't have authority to change" . I tried live chat: no response. I tried the call centre: 1st time I held the line for more than 30 minutes. When the agent eventually answered, the quality of the line was so poor, we could not hear each other. The 2nd time I held the line for more than 15 minutes and I was just cut off. I tried to lodge a complaint ,but the system does not accept it because there is no document to attach. I tried to visit our nearest branch (Brooklyn). They did not allow us in. They referred us to a branch in Centurion, which is on the other side of the city from us. I get the impression that SARS does not want to help, BUT THEY WANT OUR TAX MONEY. NOBODY wants to accept responsibility. It is always somebody's else that must do the job.
