Dear Sir,
It attracts offence under section 415 and 420 of Indian Penal Code. If you are ready then get all the addresses of Directors of Purvankara Company and file a private complaint under sectin 200 CrPC. They are bound to refund the moment they receive legal notice. Then file another case before the Consumer Court.
