Vatika The Seven Lamps: Possession delays ka kya scene hai?

My kids' school admission is due next year and I need to finalize a flat soon. Looking at Vatika The Seven Lamps in Gurgaon, but possession delays ki tension hai. Has anyone faced issues with their timelines? Builder communication during delays kaisa rehta hai? Also, quality issues ka kya scene hai at possession? My wife wants a safe neighborhood for the kids. Is their promised delivery date trustworthy?
