Consumer Redressal

I am Ranjit Kumar Jha. I have booked my house in Unihomes-1 Noida Sec.117 in June 2009 with promise of possession in June-2011. Even after delay of of 26 months, there is no chance to get possession in next 18 months too. I booked the flat in June 2009 believing that buider will keep its promise of giving possession in 24 months. Recently NCDRC has given a decision on same case in Gurgaon. Please advice me how can I go ahead and file a case against Unitech to get the house early and compensation which I am paying as Rent and EMI amount. Please help in this regard. Thanks, Ranjit Jha
