Online booking system is a ****

We've been trying for weeks to get a slot on the system to book a learners for my little brother, every Tuesday we are there but the system will only show 1 slot in a town or suburb that is far, you click on that slot and at the end it tells you it's already taken. It happens all the time. Now we sent the boy to Centurion Traffic department, and they're sending him away and asking him to book online and nobody gives a rat's ass that the system literally doesn't work.
