Capital Infratechomes delayed possession again! What to do?

I'm so frustrated with Capital Infratechomes Pvt Ltd! They promised possession in Sector 117 by Dec 2023, now it's pushed to June 2024. This is the second delay! My EMI and rent are both going. I've heard RERA complaints don't always work. Anyone else facing this? Should I just sell at a loss? What are my options? Thinking of shifting to ready-to-move, but scared of resale value. Any advice?
