Incomplete project

I have purchased a flat and alive a bank loan but due to poor management of builder project is in incomplete status. I am paying EMI since sep 2014 project was started in 2012. I paid all my dues including advance maintainace for 2 years he handoverd me the keys but project surroundings and amenity are not completed like lift, campus,street lights, some of flats in the building, few buildings in project are also incomplete, electric metres are not installed, water connection is not given. My bank had 100% disbursement to the builder. Now my concern is neither I have received any OC nor CC. I have also not received my payment receipts for last few transactions. I am paying the EMI which I want to stop because I am not staying in the flat and paying rent for my current home. Project is not rigistered under RERA ACT is there any possibility that we can register it under RERA. Builder is not coming in any meetings to discuss the issues. How do I can handle this iaaue. We tried to file FIR as well but looks like something is wrong and we ended up with meeting dates with builder and police. Plz suggest how we all members are get rid of this problem.
