Hidden maintenance costs at Ireo Gurgaon Hills post-possession

₹7.66 Cr dekar, Ireo Gurgaon Hills mein just moved in. Possession ke 2 mahine baad pata chala maintenance mein kuch hidden costs hain, brochure mein nahi the. Builder ne bola tha sab included hai, but now asking for extra common area electricity. Yeh toh RERA violation hai na? What did others do?
