Comair/Kulula/Discovery vitality website errors are costly exercise to the consumer

On the 08 March 2022 I made a booking with Comair via Discovery Vitality page, at the end of the booking I received SMS on my phone confirming a deduction of the amount from my credit card. However, the website could not provide me with Flight reference number nor the ticket, it gave me an error message. I sent an email to Vitality and Kulula trying to resolve the issue. On 09 March 2022 after waiting for feedback for long time, and knowing that the flights were going to increase with time, I decided to secure a flight by booking again. Vitality/Comair only responded to my request on the 11 March 2022 via email. When I tried to call them to resolve this expeditiously, I was put on hold for 14 minutes. and my request could not be acceded to, which is to change my flights to the early one which I initially wanted to take. the flight was cheaper. I was told to pay flight change fees. Basically it means I should pay for the technical errors on the their website, notwithstanding the more than R1000 I already incurred for booking another flight.
