Any independent or opposition-leaning newspapers willing to expose the corruption and to tell your story?
You might have more luck with that if you got one in the UK to do it. I'm sure the Dutch Embassy people read the news.
I did this to expose the corruption that was happening in my case. The local MP (Mo Mowlam at the time so no lightweight!) promised to help, and publicly swore to get rid of it but she was defeated because in the UK Coroners are answerable to no one.
Done 4 newspaper articles and a piece for the TV news and still nothing has happened!
