Alchemist Infra Realty — Payment Not Received Even After Maturity

My father (Late Uday Kumar Laha) invested Rs. 1, 00, 000 in the aforementioned company on 23/07/2010 in my mother's name (CHAMPA LAHA). We were to receive not less than Rs. 3, 00, 000 after maturity on 23/07/2019. However, when I went to their Asansol local office I didn't get any assistance from them and after few days their office was completely shutdown. Please assist me in getting back my due.
