Incompetence

Good day

I am highly dissappointed with your service. I booked 3 tickets to Durban from Johannesburg on the 13th of September 2025 scheduled for the 3rd of October 2025. On the 2nd we received a notification to check in which we did and even got the attached boarding passes. When we got to the airport on the 3rd of October we were told that we cant board because our booking was cancelled. If our booking was cancelled how did we manage to get boarding passes? It was a stressful experience for us, we were highly inconvinienced. We had to rebook and parted with a lot of money because of your incompetence. I am highly frustrated and will never use the airline again.
