I am very disappointed in Fly Safair I booked a flight and to Johannesburg

I am very disappointed in Fly Safair I booked a flight and to Johannesburg. It was my first time booking. I unfortunately did not check the date as I was so excited to get low flights. I then booked departure 04 Oct 2025 and return 11 October 2025. My graduation is 30 September 2025, so I meant to book 29 Sept 2025 and return 01 October 2025. In just 5min I realised my mistake and wanted to correct it, they tell me it will cost me R2200 to change the dates. In just 5min, your policies is really pathetic ripping people off. 5min mistake cost me R1200 cancellation fee and the rest of my money is in a voucher with Fly Safair. Today I booked other flight with the correct dates it cost me an extra R1509. So in total I lost *R2709* or should I say I paid *R2709* extra for flight to Johannesburg. It was an honest mistake/ human error whatever you may call it. I am not happy to loose *R2709*, most of us is battling to stay afloat now I have give away *R2709* to an airline.
