Contact what yjt recommended, as it seems no one is specialized in issues like yours.

Also, as your father was not at fault, I believe the other driver's insurance company should cover for the most part of your losses.
But thing is, you're in a foreign country. They will try to walk over you, when you don't know your rights, the rules, regulations etc. That'a why I say it again: you need professional help and not forums like that.
