Shocking customer service

My flight was booked for Friday, 14/06/19 at 18:00pm. After being delayed twice, the flight finally left at 19:40pm from Durban to Cape Town. Due to poor visibility in Cape Town, the plane was unable to land when we arrived, and so the flight was diverted to Port Elizabeth. On arrival in Port Elizabeth the plane sat on the runway for close to an hour before a decision was made to fly back to Durban as the visibility in Cape Town had still not improved, making a landing impossible. On arrival back in Durban we received extremely poor customer service from the Bristish airways team. There was a very long queue consisting of hundreds of people waiting to receive information regarding the plan for the flight to Cape Town. As it was 01:30am by the time we arrived back in Durban, I assumed that there would be some kind of accommodation provided, especially seeing as the British airways staff could not give us any indication of when our flight would be departing again for Cape Town. The first 30 people were provided with hotel rooms and transported to their accommodation, but the rest of the queue were told that unfortunately there was nothing that could be done to help us. This left us stranded in the airport for the night, which I found completely unacceptable!
