Disgusting delays

Flight BA6225 JHB to DBN 09/12/2019 Disgusted with the flight and their incompetence....people was supposed to arrive just after 6:30pm in Durban but instead arrived practically at 8pm. A brief apology does not compensate the time taken for delays and costs involved for arriving so late at the destination :-( offering free alcohol and a cheese bun is so insulting considering you people claim the delay was because of stranded staff at Victoria Falls. A good airline should have realised this by latest 4pm and sent a sms advising of the delay. To sit at the boarding gates for over an hour is absolutely unacceptable. The fact that this could have been easily been avoided brings concern about the future of British Airways in South Africa!!! The worst thing is to have an autistic child who does not understand these problems and to be provided such unacceptable bribery for the delay was shocking! As far as im concerned we should have been compensated for our flights costs.........not free alcohol and a cheese bun :-( disgusted........... Dont think i will choose airways ever again..............
