Terrible service/Dysfunctional website

The website experienced numerous technical issues during the birthday sale, which significantly affected the booking process. While attempting to purchase my flight ticket, I encountered repeated validation errors before I was finally able to proceed with payment. In addition, the page refreshed on its own multiple times. Unfortunately, due to these glitches, I did not notice that the selected locations had been swapped, resulting in the departure point changing from Cape Town to Lanseria without my knowledge. I cancelled the booking within minutes of purchasing the ticket, yet an administrative fee was still deducted and only a voucher was issued. I requested that the administrative fee be refunded, as the error was clearly caused by the instability and malfunctioning of the website during the sale period, not by negligence on my part. I also wish to point out that I purchased the ticket during the 30% birthday sale, so I am not demanding an unreasonable refund. As a paying customer, it is extremely disappointing that the airline continues to disclaim responsibility for recurring website issues that appear to happen every year during these promotional periods. The experience has left me with the impression that the airline profits substantially from administrative fees in addition to the numerous extra charges imposed on customers, including mandatory seat selection fees added to the total cost. This was my first experience booking with FlySafair, and it has been highly disappointing. I have received far better service from other airlines and will not make the mistake of booking with FlySafair again.
