Sizzle Properties — malur sizzle atlantis

Address: 290, 6th Cross Rd, Vijaya Bank Colony, Banaswadi, Bengaluru, Karnataka, 560043

Hello greetings!
Malur sizzle atlantis that was brought 6 years back, the seller (Atlantis) promised a bunch of developments and signed a development agreement, but nothing has been completed even after six years. The land is so barren and looks exactly how we brought. Need help as they are not responding, or even if they respond they say they dont have any money to develop. We are not able to sell at purchase price also even after 6 years of purchase.
