Ireo Skyon: Why are amenities so different from the brochure?

Possession for my 3BHK at Ireo Skyon was in March, and honestly, the reality versus brochure promises is jarring. The 'state-of-the-art clubhouse' is half-finished, and the swimming pool is always green, not blue. We're paying ₹18,000 for maintenance every month, but the gym equipment is often broken, and the 'multi-purpose hall' is just a dusty room. It feels like they just ticked boxes on paper, not actually delivered usable amenities. My kids' play area also looks unsafe with broken swings. Is anyone else at Ireo Skyon in Sohna facing this huge gap? What did you do to get the RWA or builder to actually deliver what was sold?
