Builder is not willing to pay the amount order by the Court

We bought a house from builder Arun Shelter Bangalore in 2014 with a down payment of 11 lakes.They changed the entire project just after 5 month of launch and didn't get appprovsl for the same so stayed the construction. So we tried to withdraw from it and asked them to return our money but they refused saying they don't have money to return. We filed a case in consumer court and civil court : civil court has launched a warrant against the builder and in consumer court last month after one year gave the decision to return the amount with interest in 15days. The builder approached us asking us to sign a paper in which we agree to get the principal amount without any interest but we answered them saying please follow the orders or court. We are not in India right now and so don't know what to do. If builder can take the advantage of the situation? We appeared in all the hearings of court for 1 and half year but nothing happened. Now we don't know how to proceed.
