SAA is the worst airlines

Myself and my daughter approached SAA boarding gate 15min prior to departure on OR Tambo International on 5 October 2021.As we approached, the 2 female staff members looks and says " you are late, our next flight is 18:15, go to tickets sales and purchase tickets" and then walks to the gates and closes it and the sign changes to close. Refused to let me board the the plane and this is while there supervisor was still on the plane and came off about 10min later. After that all SAA staff and manager gave me such pathetic service it was unbelievable and also refused to refund. The managers was not even dressed as a SAA employer and not even a name badge with a lack in customer service. I had to look for my luggage which I eventually found standing in arrivals unattended. I tried everything and eventualy had to purchase 2 new one way tickets from British Airways which costed R4500. They should have let me just get on plane as it was possible and I was on time but I guess they looking to make money some how. The worst experience I have ever come across regarding customer service and being denied to board my flight which I was on time for, costed me alot of money which clearly they don't want refund. FLYSAA said they would investigate but obviously coming back with reasons to cover themselves. Clearly according to news, social media and ratings, SAA is the worst airlines. Pls if you can, do avoid flying with them. Its for your own good.
