Living in our own flat 3 bhk since 2011,builder not fulfilled promises as per brochure and as per sanctioned plans,many deviations and violations were not addressed despite of legal notices.Handing over of property still pending.Many promises were ignored by builder though we all took physical possession of flats. Major fire accident happened last year in a flat and no fire provisions are in place at all.Conveyance deed not done.Auto sprinkling system not provided.Common amenities not handed over yet.All efforts to resolve amicably are in vain.Total no. of flats in this gated community of aprts 235.Contemplating to approach consumer court. Pls advise the best way forward.
