Cheating by taking money

This institute has a head named Amit. He takes rs.3000 for each student for their final year project. students join in groups of three and four and each project is worth Rs.9000. But the project we get finally is a piece of crap. It does not install , does not work, there are thousand errors and if we go back to them for they escape to other cities.They promise us to give project report full but at the end say they have not promised. This institute gets about 200 students minimum for this project. so the sum they are getting is 60,00,000 Rs. most of the students stay in hostels and are scared to speak out. Now what should we do?
