POOR SERVICE ON BRITTISH AIRWAYS

We were booked on BA flight BA0056 from Johannesburg to London with a connection flight BA 0432 from London to Amsterdam on 3 June 2023. We received our boarding passes for both flights when checking in. On arrival in London we were informed that the connection flight BA0432 was cancelled with no reasons given. After about an hour we were put on a different flight with KLM more than a 3-hour further delay. This is now with an assisted passenger in a wheelchair which was booked in advance. After the long wait we arrived at our destination just to find that our luggage was not transferred to the new flight. We waited 3 days for our luggage to arrive. This was but the tip of the iceberg. Our return flights were again on BA on 19 June 2023. This was again a connection flight from Barcelona on BA0481 with connection flight in London to Johannesburg on BA0057. Our flight was delayed for more than 2 hours so we missed our connection flight which was supposed to depart at 9:15pm. On arrival with our assisted passenger our gates were closed, and we were referred to an other terminal with NO assistance from BA to see if they can get us new connecting flights. They got us a flights on Virgin which was supposed to depart at 11pm. Again with no assistance from BA we set off to new terminals with our passenger in a wheelchair and after going through the security checkpoint we arrived at our gate just to be informed that the gates have closed, and the flight have departed. Going back to the BA offices we were assisted by a very friendly employee of BA who initially informed us that all hotels were fully booked. In our traveling group of 7 people - 2 were 82 and one 76 years old of one were in a wheelchair. After complaining they found us a hotel and also issued us with meal vouchers and bus transport to the Hotel. The problem was that by that time it was already after 12pm so we could not use the meal vouchers at the airport because the restaurants closes at 12 as well as the busses doesn't run after 12pm either. Arriving at the taxi stand (black Taxis) we were informed that they also doesn't run after 12pm and we should phone for an UBER. It took us more than 20min arguing with the lady to organize us a Taxi to the hotel. We eventually arrive at the hotel with our booked assisted passenger after 1 o clock in the morning. NONE OF OUR GROUP WILL EVER FLY WITH BA AGAIN. WHAT A NIGHTMARE
