SARS poor service

I try to make a appointment with sars by phoning them and request a call back when they call back I have to repeat my id no up to six times and every time the guy on the other side read it different back to me I then try booking appointment by SMS The response is I am not a registered tax payer I am working now for 37 years for SAPS and every month I pay tax I received last week a SMS from sars. Regarding a notification that they send me Now I want a appointment with them now suddenly I'm not registered and by phone personnel of sars can't do their work properly over the phone how difficult can it be just to take down a id number over the phone Jan Britz ***
