How to deal with non delivery on the part of supplier

I paid Rs. 46000 in cash and sofa cover worth Rs.10000 to a local sofa manufacturer. This person is known to my sister who is an interior designor. Since he had already worked for my sister's assignments on contract basis, we placed an order for sofa for our home. We paid him in 3 installments and he kept assuring us the progress of the work. It has been almost 8 months. He has not delivered the sofa yet. We have made hundreds of calls. He keeps on postponing the delivery date. I approached police station. The police officer called him to appear at the police station. Police has called him twice and he does not appear at the police station. As part of evidence we have phone recordings where its clear that he has received cash from us and he has not made the delivery. We dont have any other written agreements. What measures can effectively settle this case?
