I made a mistake by investing in Mantri Navratna. it is the biggest financial mistake of my life. They simply not even bother to reply to you once you book the apartment, except for payment.
Their staff in Chennai Lokesh talks as if he is a Ladu labakku dass, doesnt even have the courtesy to talk politely with customer. The project is delayed by almost 4 months from 15-mar-2013 to 30-june-2013 and the Mantri staff doesnt give explanation for this delay.
After coming in contact with one of my friend who also unfortunately invested in Synergy, I am worried about the quality of the construction. even GOD cannot save me from these money monsters.
