Delhi Heights — Refund for the amount paid for the land cost for 3 BHK flat

Address:

Dwarka, Delhi

I have registered for 3 BHK flat (HIG) through online link in year 2018 and there was a lucky draw, my name qualified in lucky draw list and I had booked for the 3 BHK flat (HIG) I have paid around 21 Lakhs till May 2019 for the total land cost of 3 BHK flat (HIG). The company is not providing proper status, they are fooling me saying land pooling is not completed but initially they have told in the advertisement that the flats will be available by end of 2019 but land itself is not occupied, where the hell flat will be ready.
I want my money back as soon as possible as I belong to service class and can't effort to loose such big amount which is my life saving.
