Why won't the developer let me get the key to the new house?

I have signed a commercial housing sales contract with the developer. The five certificates of the community are incomplete because the community is in the development zone. Not only does this community have no documents, but all communities do not. I believe this is a * * * * world, so * * * * will definitely solve the housing problem for us.
