I haven't used the train since
So it is effectively a sample size of one?
It's just that your experience seems at odds with most people's. East Coast (in the form of various franchises over the years) have been one of the best operators for some time, quite consistently. I travel by train quite a bit and it's very unusual that all toilets would be out of order on a long distance train. Did you ask the train staff? As you hint, using the ones in first class would be perfectly reasonable if there were no others available (although the story seems to have changed now - there was one available after all).
I think there is a kind of road rage equivalent that afflicts some people when they go on the train. I know that lots of things could be better about our railways but sometimes people's outrage seems out of proportion to the actual nature of the problem. If you got delayed by an hour on a seven hour car journey would you swear never to drive again and demand your petrol money back? I think the compensation scheme for rail delays in the UK is quite generous really. Like others have said, you wouldn't have much hope of getting money back from an airline, or long distance bus operator.
