Centurion Mall Ticket Paying Machine is overcharging Customers

Dear South African, please be aware that the centurion paying machines for tickets are not charging us correctly as per the rate schedules on the paying machines, 0 to 30 is free and 30 minutes to an 1hour is R5 BUT i have been monitoring all those paying ticket machines, for less than 30 minutes they charge you R0.00 and from 30 minutes those machines charge you R10. CAN THE CENTURION MANAGEMENT CHECK THOSE PAYING TIKET MACHINES PLEASE AND SET THEM CORRECTLY ESPCIALLY MACHINE APS 36 AND APS 37.
