Mt Technologies — cheating in the name of legal action

Unlike you ppl, i have almost given them 75000 in the fear of legal action. They said the case is closed with everything done. And they asked 11000 to send the closed case details by courier which i did. After 10days, again some other new person is calling today and starting the same from the first.
Don't know what to do. What a fool.in the intention of earing money, now standing after losing what i have saved these days.
