British Air is not paying compensation for flight cancellation from London to Miami and despite following up ignores their customers

British Air cancelled flight number BA207on 6 Feb 2024 due to mechanical problems. I app**** for compensation for this cancellation both for myself and my wife on their web site. I got a reply that they would pay me on 9/04 that they would make the payment. I have followed up at least 3 times and am still waiting for a payment. My follows up are being ignored. I also lodged a claim for lost flight and accommodation in my wife name (as she was travelling with me) and received a reply stating weWe're sorry we've not been back in touch about your Customer Relations case and we appreciate your patience on the 5/05 2024. After frequenting follow up, I still have no reply. The overall service is extremely poor, and it is hard for me to believe that tan international company has no respect for their clients and just ignores them hoping that they will give up.
