Expat Properties — tala valley plot

Address:

Mumbai City, Maharashtra, 400706

I had bought a 1acre plot in their tala valley project in feb 2013, under emi scheme for 5 yrs, which completed in feb 2018. However, the registration of plot is not yet done. And they are saying that the project has been cancelled. When asked for money refund, some receptionist lady in mumbai office said that it cannot be done before jun 2020.
Need to file a legal case now against these fraudsters.
