Sanctity Hi-Tech has failed to deliver houses even after a long delay. The harassed buyers have approached RERA for refunds and cancellation. Sources said almost every customer has filed complaints against the developer and the final decision from UP-RERA is now awaited. "No development is seen at the site. Since Suncity has not started any development in this area, I am afraid that they do not have any intention of developing the plot and plan to dupe investors of their money", said a homebuyer, Varuna Gupta.
