BA does not care about customers

I travelled to Europe in September and was delayed for 4 days due to the pilot strike which necessitated me spending money on accommodation, food and transport. I submitted a claim to BA and am still waiting for a resolution. I have sent many emails and made at least 4 overseas phone calls and been left holding for in excess of 20 minutes before being able to speak to anyone. They make lots of promises, but nothing actually happens. Don't believe their fancy advertising and their messages about how important customers are! British Airways does not mean what they say and they don't really care about customers.
