Today I approached to buy a flat. They do continuous followup and arrange vehicle to visit the place. They offered a good package too. Also another attractive deal is, they gonna give money every month (approximately 11k) towards rent to stay until the building complete and ready to occupy. Else they give a flat in existing tower and they will pay rent to the respective owners. Not sure how far can we trust these promises after reading all these reviews. We middle class people put our blood to earn each and every rupee. But will scare to enter oi such kind of deals.
