AMR Infrastructure Cheated Customers

I have bought two commercial shops worth Rs 34 Lakhs in July 2013 with 12% assured return From AMR Infrastructure's The Great Adventure Mall, Greater Noida but now they are not paying assured return, not constructing the Mall nor ready to return booking Amount, When I starting visit there office in Karol Bagh then came to know they have fooled thousand people like me, So I decided that I will try to expose them so they cannot cheat more people like they have cheated us.
