I doubt whether there's anything much you can do to improve the situation there. I remember a Qantas 767 a few years ago, was given clearance to descend below their LSALT whilst on descent in to Denpasar from the north. Good thing there was someone alert in the cockpit.
What you could do to help other pilots, Massey058 is to give an account of the actual problem you encountered with ATC. Was it a misunderstanding due to language comprehension? Or was it something else? At least this will help to give a heads-up to other pilots in the future.
