[Resolved]  Fini Technology — data entry job

This guy called naresh patel from fini technology messaged me to make a one time payment of inr 299 to get data entry job. He said he would register me and create an id for me so that i could get data entry jobs to work on after i made the one time payment. He hurried me to make the payment stating that it is a government data job. I did make the initial payment, but right after ten minutes i messaged him and told him to cancel my registration post reading reviews on google. I also told him to keep the inr 299 but to cancel my registration. I had not received any legal or binding documents from him when i requested my cancellation. He then demanded that i pay inr 10, 000 only then he would cancel my registration, which had not happened till then. He then threatened me that he would send me a legal notice. There has been no legal documents sent to me or there has been no acceptance from my side. How can he threaten me to pay money for a service that i have not even availed. I have the complete whatsapp chat history. But he has gone ahead and deleted the parts where he is demanding inr 10, 000. And after an hour of this chat, he has sent me some document in my email that i haven't even checked. He also kept asking me to send a photograph for him to cancel my registration. He also has my aadhar card details. But this is sheer harassment. He should not be doing this to people who are desperate for jobs and need to earn some money for their needs. Need help.
