Renewal of Drivers Licence Card Nightmare

Actually they do not deserve a star at all. I visited the Centurion Test Centre last week to make an appointment for the renewal of my Drivers Licence Card. There I find a notice on the door, stating that appointments can only be made online (https://online.natis.gov.za). IF by sheer luck, you get to the second page of the booking, there is not one single Test Station in Pretoria available from the drop menu, to select. There is also no answer at their call centre. It seems that it's easier to not follow the Law.
