Son 16 not picked up in Kimberley

I booked my son on the bus from Kimberley Shell Ultra City on 20/06/2015 to depart at 01:55 and at 04:00 I got a message from my son who was standing there alone saying that the bus hadn't arrived to pick him up.<br> I tried phoning the customer care line and held on for 15 minutes without speaking to an agent. I had to organise money to go and fetch my son after purchasing two tickets with a return trip for the 18/07/2015.<br> I am very disappointed that not even a sms was sent saying that the bus was running late or wasn't coming. I purchased the tickets via computicket and the references are B39B15AA / L379M8FK. The other people waiting there phoned and were informed that the bus is on its way but never arrived and left. I expect a response soon and I expect a refund for both tickets as I will not be using your service ever again. Please advise soonest as I need to organise for my son to go back to Kimberley next month.
