Advance for property

Hi, I am an NRI. Before demonetization I booked a villa in Coimbatore, Tamil nadu. I enquired about the builder and saw his projects before booking a property. He had all his projects in acres. This particular project was also proposed to be 35 acres and funded by SBI. Seeing all this and trusting the bannk's scrutiny 3 yrs back I booked the property by paying 9.2 lacs. And had to pay remaining 3 lacs so the rest will be loan availed from SBI as agreed. Before paying this 3 lacs I had to go abroad so I asked for a time of 6 months so I can pay this amount and sign the loan papers. When I got back all this demonetization and dtcp approval problems started. I had money but I waited for all these problems to settle and his project to start before I pay more. But as I suspected he had lost the money during demonetization and SBI has freezer all his accounts. Now I am stuck with 9.2 lacs with the builder. I have not signed any agreement or any legal papers with the builder. I only have the advance payment receipt given by the builder. I don't know what to do and how to recover this amount? Pls advise
