Just got possession, super area trap is real.

Super area trap is real, and it's a major scam. Just got possession of my 3BHK in Phi IV, Uday Realcon ka project. Matlab, brochure mein 1500 sqft super area dikhaya tha, but carpet area hardly 900 sqft nikla. Yeh toh hadd hai! Builders aise numbers inflate karke kaise bech dete hain? Mera toh sar ghoom gaya. Yeh log PLC aur floor rise bhi is inflated area pe charge karte hain na? Feeling completely cheated. Has anyone else faced this carpet area vs super area ka game in Noida Extension? How do you even fight this after paying everything? Koi advice do yaar.
