Adel Landmark — non possession of apartment after 8 years of booking

Address:

Gurgaon, Haryana, 122001

After retirement i have booked a house in their project skyville sector 68, gurgaon. I have paid almost 60% of the total money. There has been no construction at the site since last 3 years. I have been continuously writing to them but did not get single response. Under the situation i want to pull my money out from the said project with minimum 18% interest.
