Google Why? Why Google?

I have 500+ search results (each day) from Bing and Yahoo but none from "not provided" Google search.
I've checked google webmasters tools and everything looking fine. Good index status, No manual webspam actions found, sitemap submitted excellent
is there a google search sandbox somewhere i can take a look at my site why this is happening?
not even a single search result show up.. not even in the 500th page result. I dont do anything illegally nor black SEO what so ever.
please help me…
