Sushma Surana — Returns on investment on property and possession not received after making full payment

I have invested in tower B of Gift city. As per the agreement I have made all the payments on which I was assured monthly interst on my investment amount. Not only the authority concerned not paid the interest but also failed to give us the possession of the unit promised. Now there is no communication from their part. Such a big and prestigious project is ooling the investors.
