Consumer Redressal

Dear Sirs, At the outset, I convey my respects and regards to the admin and managers of this Consumer Rederessal Forum in web based platform. I in the company of around 50 people booked a flat at the outskirts of Kalpakkam, a well known nuclear installations township way back in 2011. More than 3 years have elapsed and the builder has completed only about 50-60% part of all the houses, that with much delay and hold ups. It seems he has finanacial problems and he has been prologing the resumption of construction. Nevertheless we have all records and minutes of meeting which contains our deliberations and his committments.Now almost we have lost confidence in him and no more delay is useful to our cause. Most of the members are suffering from heavy interest burden from Bankers and some of them are rendered homeless after retirement. Pl.suggest how we can proceed with the matter . Is police action or legal remedy possible to achieve our goals now that we have exhausted all our efforts?
