HI friends, i am in trouble & i am seeking true guidance here.

I am working for a IT company based in noida. in april, they sent me
to germany for some project work. they make commitment to
give 3000 euro salary here in germany account. out 3000, we are getting around 1800 euro after tax to german govt. we don't have
anything to do with tax return here[as our company words]. company commits us to provide 900 USD for compensation towards Taxes in germany. But problem is that we don't have any written proof for this commitment. Till matrch 08, company paying 900USD to our germany bank account for tax compensation. Now during Aug month, we are supposed to get 4500 USD for compensatition towards Tax for 5 months from april - aug. but now company is saying they will give us 450 USD as euro/USD rates skewed up. Guide as how to get our complete money back from them. they are saying we applying policy from fiscal year starting from april 08. how can they apply policy now to time that is already passed. From my opinion, they can apply policy from now onward. if they want to apply from april 08, they should inform us in april but they are informing us now. please help us in saving my hard earned money. moreover they took around 12-14 hours a day in germany. please help us.
