4 years waiting for possession in Sector 107

When will KCC Contractors & Engineers in Sector 107 actually deliver possession? Booked a 3BHK for ₹1.2 Cr almost 4 years back, kids ki school admission ka time aa raha hai. My wife's priority is a safe, ready home. Brochure mein 2-year possession bola tha, abhi tak kuch nahi. Matlab, under-construction lena kitna bada galti hai? EMI bhi jaa rahi hai, rent bhi. Is this normal for Noida projects? Anyone else stuck with them? Kya karein ab?
