Consumer Redressal

We have purchased a plot from Vatika India Ltd in Gurgaon in development linked plan. They were supposed to give us possession of the plot after 3 years but after 5 years now they are offering us possession of the plot and asking us to pay the final installment which was due on possession. But Vatika is saying that they can not facilitate the sale Deed of the plot and hence we can not construct any building on the same plot as they do not have the required approvals to facilitate conveyance deed for that particular sector. We are asking them that we would like them to do the sale deed of the plot along-with the offer of possession. They are saying that registry ( sales deed) could be possible only after 4-5 months and you have to compulsory take the possession of the plot and pay us the amount due at the time of possession. But the irony is that we can't do any construction as they do not have required permission for the Sale Deed to take place.
