Consumer Redressal

I booked a residential1 bedroom flat with Sairung developers in Pune in 2007, and made full payment of Rs 29 lakhs then. The builder refused to give posession to me, and infact started as service apartment project there in the Name of Spree Longer ( Now changed to Spine longer) in Jan 2012 and started renting out my flat without my knowledge and permission. When I asked for possession again, he refused saying I have to sign an agreement with him to rent out my flat. I put in a police complaint in jan 2014 and based on that the Builder agreed to buyback my falt for Rs 35 laks, to which also I agreed though a huge loss to avoid a case. We signed a MOU and he gave me cheques for Rs 35 laks, all of which were dishonoured. I again approached the police in oct 2014, who forced the police to hand over possession to me after vacating the guests in the apartment. The builder again approached me to buyback the flat for Rs 42.5 and I have done that. I would now like to file a case against him
