Terrible parking vendor machine system

Centurion Mall parking vendor machines are very terrible. The Mall advertised parking to be free for less than 30 minutes. If it happens that you leave the Mall within 30 minutes, the vendor machines display "Unreadable Ticket...". You call for assistance through the vendor machine which will also take minutes to be answered and thereafter you will be told to remove the ticket whereby you will be issued another ticket for R10. If you park for over 30 minutes your ticket is accepted with a stipulated price and don't experience such delays. If you are in hurry or plan for a quick shopping, avoid Centurion Mall just because of the vendor machines not the shops.
