We are living in our new flat since Sept 2012. However builder is about to receive completion certificate from Muncipal Corporation of Pune. Therefore till date no possession letter given by builder. Also no amenities including drinking water, play garden, Gym not provided yet. As per agreement possession date was April 2012. Can I make complaint to Consumer forum ? or shall I wait till possession letter ? Shall we accept possession letter without amenties ? Kindly help.
