Consumer Redressal

I booked one flat in high rise of Ramprastha builder gurgaon in aug 2010 and I was assured to give possession in Aug 2012.. Now after 2012 , I started chasing them regularly but I m still struggling hard to get any resolution from them. I only get false commitments from the team there . I am into private job and can't afford to pay rent where I m staying for the last 3 years due to the delays by the builder. Moreover I hv been paying monthly installments for.the last 5 years and now I am broken down with my life's other financial obligations . I am diabetic and going through stress ful life. Looking forward to get some relief now with hope. Kindly let me know how can I get the justice. Kamal Malhotra
