Prospexiv — demanding money

On 02 january 2019, i was a promised for a earning oppurutity online for free, now they are demanding money in name of legal action and extension of work.

The agent told me the job we are given is totally free, if you complete this work you will get rs 30000 per month and the service fee would be 4600 which we will deduct from your salary, but i told them i am not interested in your work then, the agent told me to cancel your work provide your aadhaar details and your mail id, the prospexiv fake company is still mailing me to pay rs 15550, or else the wil register case against me.

Please help me to solve this problem
