British Airways lack of service

Flew BA business class in July from Cape Town, London, Torronto, Vancouver, London, Cape Town. Paid close on R150 000 for 2 tickets. The most shocking experience of my life. Seat configuration is appalling. You are facing a stranger, in our instance, as 2 seats face back and 2 seats on either side face front. In other words, you have to step over someone's legs to gain access to the aisle if seating in the middle 2 seats. My mother has 10 % vision and is 76 years of age. Needless to say this proved to be challenging, even for an able body. Seats were narrow in width and upholstery worn and weathered. My headphone plug points were faulty on 3 of the flights. On our last leg from London to Cape Town, we took off at 10pm and only got drinks and food service at 1am! Then were told that they had run out of fillet. In business class you should NOT be running out of anything! Told them to find fillet and low and behold, 2 fillets miraculously appeared. Convinced they were put aside for staff however after my expressing my absolute disgust with the service, we were served fillet at 1am! Planes are dated and interior very run down. Toilets were tiny and no different from economy class. I need to ask what we were paying for?? I could have flown first class with Emirates for the price we paid on this inferior airline. Business class lounges were non existent and we were put in economy class lounges where we experienced shocking service once again. In London on our return we insisted on been taken to the Quatar lounge as BA just could not produce, once again. I put my complaints in writing and got a stock response apologising for not getting the seat I requested and unfortunately they cannot offer my anything in compensation, as per my request! None of the above was relevant to my complaint at all. I told them not to bother as I would never be flying with them again and will take this to social media to warn other travellers. I once again received a stock response apologising for issues that I had not even mentioned and once again telling me I could not receive anything for free!!!! Not once had I requested anything for free or any compensation. Worst experience of my life and managed to spoil our entire trip. BA if you charge the prices (and most expensive airline for business class) then up your game! Be warned fellow travellers.
