Do not use British Airways

I was on a flight that was delayed in London in June this year. We were basically asked to leave the flight just after midnight and to sort out our own accommodation until the flight was rescheduled. The flight left the next day 24 hours later. On my return to South Africa, i have been trying to submit and complete the claim that can be made for the delayed flight. British Airways just automatically closes my claim (now claims) and provide no feedback. The atrocious treatment we received that evening, including the elderly and infirm just highlight that British Airways is an uncaring and callous airline that is only interested in profit and not people.
