Fraud done by a private company

Hi, myself Akansha Sanoria, I two months ago had a conversation with a private company representative about the home based part time job. The company is Easy Data Solutions in Delhi. They made me believe that they will be providing a typing work of 400 pages for which they will give me a sum of Rs 16,000/-. For continuing the work I have to submit Rs 3000/- as a registration fee and that will be refunded in my first salary. They gave me 2-3 documents in which their registration form was also present. After my submission of the registration fee they provided me the work via mail. I completed my within days and submitted it to them via mail too. After a week i called them and asked about the salary they informed me that the work I did was not up to the standards and now they wont be giving me any money rather they will reject my registration too without refunding my money. They did not provided me any proof of work rejection nor they are in mood to provide me the salary for my hard work, efforts, time and money. Now they told me that you do what you want to do we will not be providing you the money. Please help me I need some advice on this matter and want to teach them a lesson so that they do not fool others.
