Desktop work clinic - Job fraud

Respected sir
I'm a student and I wanted to support my parents financially, so I tried to work from home. Sir , one message came to me from these three whatsapp numbers **********, **********, ********** . I have attached the evidence in the PDF, they also signed a legal agreement and also mailed me refundable amount file (rupees ****) which they forced me to pay in order to get income of **,*** . The job was to fill *** forms, and I did so but I neither got the salary nor the refundable amount of ****. Sir they blocked me everywhere. I told them again and again to return my money but they didn't. Sir please help me out. I am attaching all the evidences in the PDF format. Hoping to hear from you soon. I request you to please do the needful as soon as possible.
