I can't add much to what others have said already. You didn't have valid travel documents and are relying on things like leniency and reasonableness from BA and others. While things may be a little different if you were presenting yourself for entry into your country of citizenship, that's different to your problem here. I'm a little surprised that your embassy can't help more, but that may be due t the fact that you already have one valid passport out there. We can't really say because we don't know citizenship.
In any case, coming off all DYKWIA and slapping the same story on multiple travel websites is counter-productive. It won't get you home and it won't get you sympathy and help from the gang here.
