Subvention scheme Cancellation of booking

I have booked a flat in Greater Noida in 2015. I have paid 10% from my saving and 50% by the Bank. But after 2 years I got to know that the tower of project got stuck in a court case and even construction work not started. I visited builder office and asked them for refund of my money but they told me that if you wants the refund than 15% of money will be deducted as per agreement and informed me to that they are you can go for other flat in different tower. So I swapped the previous flat with new flat unit. But in agreement I found two papers addressed to greater noida authority that I am giving my consent for any change in site plan and building plan. I denied to sign these two papers. Builder also said OK and sent file for loan processing to Bank but Bank requested me that if you are not signing these two papers than loan could not be disbursed. Around one year later I enquired Bank, they told that your loan processing is cancelled as you have not signed papers. Owing to all this I do not want flat from this builder in these conditions. Then will I get my money back from the builder. And How I should process.
