Stay away from Supertech if you want to save your hard earned money. At time of booking, Supertech will tell you cheap price of flat. Once you book the flat and pay almost 90% of cost of flat on time, Supertech will charge you very high amount when you will ask for possession.
Per allotment letter I had paid 95% of total flat cost. I had to pay remaining 5% during possession but Supertech asked me to pay extra 6 Lakhs for it. No one will listen to you.
