Daylight robbery and cheating

We had booked a flat with Amrapali builder in pre launch in 2005 in their project . At that time it was communicated the launch would happen in 6 months time. After an endless wait, the project was finally launched in 2009 after
4 years. All this whenver we called Amrapali , they kept telling us that the launch would happen soon. All our requests for pulling out were turned down.

In march 2010 we came to know that the project which was being constructed was totally different from what was proposed at the time of booking and signing the agreement. I have sent around 100 emails and phone calls to Amrapali , but they just ignore our communication and do not have an answer for the changes to the project.
The following were the changes to the project.
The project size which was shown at the time of booking was 50 acre which is now reduced to only 23 acre
In the original layout plan, there were 35 towers in 50 acre project while there are 28 towers in 23 acre. So originally open area ration (0.7Tower/Acre) was reduces to (1.2 tower/Acre)
The following features were shown at the time of booking but removed later without informing the customers
Lake Garden
Lake side restaurant
Amphitheater Service
Musical Fountain
Tennis Courts
Badminton Court
Pedestrian Plaza
Clock Tower
Entry Plaza

So what was initially a luxury apartment was reduced to value/budget homes but consumers still paid the price of luxury apartment. We filed an RTI and came to know that out of the 50 acres that Amrapali had aquired for this project, the 27 acres were surrendered in 2008. Still after surrendering the land, Amrapali made us sign agreements about the project and the area of project specified was 50 acres. This is sheer daylight robbery.

Their customer service is very frustrating. One of their customer service lady called Nandita, got heated up after I demanded an answer and she said "*** off" and kept the phone.

I would advise everybody to be careful of buying anything with Amrapali . It is 2011 and 6 years since we booked and there is hardly 20 % work done on the project. All our requests for refund are ignored and on top of it the customer service guys dont talk to us. We are very soon planning a media clip on Amrapali where several of the customers who are in the trap will air their opinions.

Anybody here, can you suggest what can be done to put pressure on them to refund the money.
