In August 2010, My father sold his house in south delhi for 63 lacs and out of that money he has booked a villa in noida extension for 56 lacs. Remaining money he kept aside to pay for e rented accomodation for 2 years thinking that our villa will be available by aug 2012 as promised by the developer. But now after all the drama, he is extremely depressed. What shall we do?
