Can I fight to get my money back..?

I invested 6.40 lakhs rupees for student visa in a Singapore based college, initially I was not willing to go but the reason which motivated me to go there was I have been told by my consultant that you can work and there will be placement after the course is over. But on going there I came to know that a student is not allowed to work neither there was college placement. I want to sue them and get my money back for bluffing me. In the mid I wanted to decline this decision of mine to go there but they told me if I step back now they are going to deduct 30% of the fees where as there was nothing like that. My fellow roommates told me the truth. The docs which I hold with me is student contract , So as I was not able to work over there couldn't pay the next installment of fees so , I was forced to cancel my visa and I feel pissed because the guy over there in Singapore college who deals with this consultancy that It was my job to check the information about Singapore rules and regulation. I just want to ask if I was suppose to know everything then what is there job ? to sit back and collect payment only, this was the most crucial information they were suppose to tell me but.......
