Gurgaon RERA: more bark than bite?

₹1.8 Cr for a 3BHK in Sector 65 feels like a trap if you don't know the builder's history. Everyone talks about RERA, but honestly, is it even effective when builders like SS Group delay? My wife's worried about kids' school admissions if possession gets pushed. Their builder-buyer agreements seem stacked against us. What are our *real* legal options if they don't deliver on time? I hear about RERA complaints, but does anything actually happen, or is it just on paper? Change my mind.
