Hello, First and the foremost thing you should do is, immediately file a police complaint mentioning all the facts and circumstances about the alleged incident inflicted upon you. As per limited details you have mentioned in this question I can only advice you that the alleged person has committed offence of fraud and cheating, therefore you are eligible to get F.I.R. registered against him. If the police does not take action then you may also approach court for such in action by police officials and file criminal case against him. Apart from that you may also seek civil remedies (civil case) against that person to recover you hard earned money. There are plenty of other civil as well as criminal remedies available to you in your matter but for that you need to consult a lawyer and have to show him all the documents and details related to the alleged incident so that the lawyer can give you precise and effective remedy in accordance.
