Consumer Redressal

Dear Sir, This is with regard to the 2 BHK flat purchased from Logix group in Sec 137 Noida in their project LOGIX BLOSSOMS COUNTY. I purchased this flat in May 2011 under flexi payment for which i took a loan. The progress was good at that time and my Tower -P structure was 50 % completed. The possession date promised at the time of purchase was Dec 2012 with a grace period of 6 months. I have been following up with the builder but they keep on delaying with some lame excuse or the other. Builder shows their false commitments and breach of trust each time. I am now short of patience and funds both. I am forced to live in a rented accommodation along with my loan EMI and this has made my life extremely difficult. I approached the builder for a monthly penalty payment so that rent can be paid, but the builder is not agreeing to monthly payment and says this will be only adjusted at the final payment, which i seriously doubt they will pay. I would like to know what legal options do I have to take the builder to the court. Also I would like to raise a alarm for the other innocent buyers who dream to live in their own flat someday and are badly cheated by these goons. Please help me on this.
