Kenya Airways in South Africa *****ing money from foreign national

My flight was at 17h50 , I arrived at the check in counter at 16h25 i waited till the last passenger was assisted then when it was my turn to be assisted the agent told me they are closed and i was looking at the last passengers bags still on the weighing machine. Nevertheless the supervisor was at a distance on a social call when she was asked whether i should be boarded on the plane or not and She ( Lydia kodisang) shouted in sotho dont book him, i was silent and listened to the whole conversation because they thought am from kenya based on my statue and dark complexion...CCTV is there to prove her actions and time on how they treat people from outside South Africa so that they can make money...Lydia then told me to go to sales only to be told to pay another R8500 for a new ticket on something that was the customer cares problem..Kenya airways is making sales on foreign nationals based on their lack of understanding and cultural backgrounds....Never book this airline if you dont have enough budget because they will reap you off, I was booked in for 01h00 flight on the same day only for it to be delayed for an hour...
