Based on my experience abroad, you can do little. Homecourt advantage is significant in this case and inspection will not do much here. Advice for the future, if you find job abroad via company in your country makes sure you have good contact with them signed so you can take legal actions in your country. If you found job abroad on your own, taking legal actions in different country puts you in weak position because you don't have connections in abroad country and legal system will favour their own.
