A new home

My family and I got scammed by a real estate developer. They've sold the building to the government and we're being asked to leave. We don't even know who to negotiate with. We're willing to pay whatever cost, but there's no one from both parties who would talk to us. Now, we're being asked to move out within a month, and it's not that easy for us to find a new place. This is our home, and suddenly it just got reduced to ashes for something we didn't do.
