Welcome to FT!
I am afraid I don't think you have any chance of resolving the complaint to the outcome you desire. BA's T&Cs are quite clear in that prices aren't honored until booked. It is just bad luck that the system was down when you wanted to book, and that the prices happened to increase the day later.
