Overcharge, STILL waiting for feedback and refund!

I pre-booked my parking at ORT (31/07/2015 - 02/08/2015, for a period of 2 days, 3hrs and 47mins), which should have cost R150. When I returned, I was overcharged. <br> <br> I sent an email sent to your customer service department (on 03 August 2015, as per the process stipulated on your website), who clearly could not be bothered to send it on to the relevant parties. By 14 August, I received no response, so I called, and then had to email all the details again to Mosele Khalo. I was then told that the information would be passed on to Dineshri Aboo. By 17 August, I had no feedback from Dineshri, so I sent an email, only to find out that she was out of the office. I have STILL had no feedback and sent an email to both people concerned. I have now received an automatic reply saying that Mosele Khalo is out of the office. I have yet to receive feedback from Dineshri. <br> <br> ACSA, SORT THIS OUT! You were quick to overcharge me, but not so quick to refund!
