Evermark Provica Dream Valley 2: My ROI projections are sinking

2.5 years past the initial RERA date for Evermark Provica Dream Valley 2, and still no clear possession. I've invested ₹50 lakhs here, banking on rental income by now. This delay is killing my ROI projections. Has anyone managed to get a firm timeline from them? Seriously worried about the resale value if this drags on.
