Feeling cheated on Vatika Premium Floors

EMI starts next month for Vatika Premium Floors Sohna. Builder ne jo dikhaya, aur jo mila, zameen asmaan ka farak hai. Brochure mein swimming pool tha, ab woh bas ek puddle. Kids play area bhi broken. Maintenance charges high, services zero. RWA kuch nahi karta. Did anyone else face this after possession? Kya karein ab?
