Supertech — no progress in project

My flat in supertech golf village is pending for possession since 2017. Now i need my money back with interest. I'm seriously worried as i have taken lot of loan for this property and that's giving me headache now.

I have paid 90% of the total cost (Gst separately) in year 2016. And there is no progress in my project since then.

I have paid almost double the amout as compared to the total cost which is really unfair.

Please give my money back with interest.

Thanks
