She refused to do that but they would deposit 6,500 Avios into my account.
Again, I should I have said something while onboard but I was trying to sleep.

Well done for pursuing. And for using some judgement on what compensation to ask for.
The reason why it's important, I think, to ensure things like this are pursued and compensation sought, is only in part to recompense the traveller. It's also because in their Management Info on complaints, BA management will be paying much more attention to those that are costing them to resolve. Even though Avios are cheap as a cost to BA, they are still something of value that BA has agreed to give away. Therefore they'll pay relatively more attention to ensuring these issues don't recur, if they can help it.
