Theresumesearch.com — Fraud company, Harassment

I came through this company for work from home opportunities and i whatsapped them that i would be interested . But after a day some family emergencies came up and i emailed them that i won't be able to complete the work and that i need an extension or cancel my agreement. They started sending me threatening emails that I have to pay 6500 rs as i could not complete their work on time. They are threatening that they can ruin my cibil score as they have my pan card and aadhar card. This has been a mental torture as we take up work from home opportunities when we are in real need of money and then these people try to extort money from us.
