Painful experience at Kulula.com

I had the worst experience ever on Kulula.com. Yesterday our flights were booked for 5h55 MN101 we left our house 2 hours earlier to the airport only to realize when we got to the boarding gates that there was an issue with our flight. We then proceeded to the Kulula counter where we arrived first but took a whole hour to book us on to the next flight because our flight had been cancelled with no communication from Kulula. Only at 5h55 when the flight was meant to depart we received sms notifying us the flight had been cancelled with phone numbers that don’t even work at the bottom of the sms. The customer service agent then told us they have a new system hence they were struggling whilst other customer service agents were helping all the white people that were behind us and booking them on to the next flight with seats that were next to each other. My partner and I were booked seats that were way far apart from each other and we just had to take it or leave it cause that all that was left and were given boarding passes that stated gate D7, we got to gate D7 but that wasn’t our flight boarding on that gate no communication from Kulula or the airport. We then had to rush all the way to the bottom to gate E7. We were stressed out, almost lost our stuff, sweating and out of breath. What an inconvenience and painful experience!!!
