Intercape - Incompetence uncovered

How do you deal with a bunch of incompetent people with useless processes to assist clients in need after THEY (the Intercape team) made an incorrect booking that has been verified by their own recording of the phone call???
Let’s start over... I made a return booking via phone for my student son from Potchefstroom to PE. After verifying both departure dates (to and from PE) I was happy with the booking and the price and handed the phone to my wife for direct payment via the phone. All done, my son got on the bus to PE on the 17th of March and arrived early on the morning of the 18th.
We spent a lovely week and on Saturday the 26th when he printed his ticket to depart that evening back to Potch we realized that the second ticket was booked back on the 19th of March (a day after he arrived) and not for the 26th as booked according to the recorded message.
This is where it becomes interesting!!! After enquiring with Intercape telephonically, they said they had to listen to the recording and will get back to us after 10 minutes... 45 Minutes later I had to phone back and enquire again. I was informed that they have listened to the recording and although I had given and confirmed the correct dates, the dates at the end of the call confirmed with my wife was incorrect... This after I told them I'm handing the phone over for payment as I was needed elsewhere and already confirmed the dates earlier in the call.
I was also told that there were only 1 ticket on the bus left to Potch for Saturday and that if I wanted my son on the bus, I had to Pay R970 to get him there. They will have to send the issue to their complaints department which could take up to 7 days and they were only available on weekdays??? I explained to them that my son had to get to Potch by Monday morning 9am and that I couldn't wait for their complaints department to sort out the issue during weekdays. After all it was confirmed by their own recording that THEY (INTERCAPE) made the mistake.
Intercape couldn't change the ticket and after being transferred to a manager which further boggles my mind and who evidently didn't have any capabilities to sort out any issues even when it was caused by their own incompetence. The inconvenienced client was just the guy who paid the money and after Intercape had received it, got absolutely zero client service and zero compassion for the situation that Intercape caused.
The end of the story. I was transferred 4 times, when asking for names I could only be given a 1st name and no other contact info, like Sharon or Tasnien. (In business, if you don’t want to give your name or contact details, you are either hiding your incompetence or hiding your company’s incompetence.) Eventually, when I had no other choice but to book a new ticket and when it was time to transferred me back to book a new ticket to make sure my son gets back in time to write his test, I got cut off and I had to phone and listen to the stupid recording again while waiting for an operator to pick up and rob me of another R970!!!
10 minutes after booking the new ticket I got a call that all the tickets had been sold and that the bus was full… They couldn’t even put 1 and 1 together to realize that the name on the new ticket was the same as where the complaint came from.
One would never want to say never, because you don’t know when you would, like in this instance, need to make use of a bus service, but for sure I would like to AVOID using INTERCAPE ever again!!!

No response received from Intercape as yet. Still waiting patiently.

What does it say about your company if you don't even have the decency to respond to customer complaints?

Just putting it out there!
