Digital Services, Latur, Maharashtra — asking and threatening for money

Hello all, the same thing is happening with me. The procedure was exactly the same first a call from farheen shaikh telling me about company digital services and offering part time form filing work from home, then a verification call with agreement email. I asked the lady if i couldn't perform the work or want to to terminate my registration within 24 hours then 'will i have to pay any amount?'

Farheen replied, 'no, if you cancel the registration within 24 hours then you don't have to pay any amount or a single rupee.'

I sent the mail for cancellation before they sent me the username and password which i haven't used, to namely their helpline id helpline. [protected]@gmail.com (This is fake because i got revert mail that the email address isn't registered at 12:30pm), helpline. [protected]@gmail.com (Where the helpline lady said there's no mail, but i have the successful submitted mail message), the email address from where they sent me the agreement, farheen shaikh's email address.

But they're all threatening me to deposit 2000rs for their cancellation charges otherwise they will take severe legal actions. I have everything in written and have all the copies of my conversations with them but i am still afraid. I don't have money to pay them. I have also blocked their email addresses as well as their phone numbers. Also, i haven't logged in into their account and requested the cancellation within 7 hours.

Do i need to worry when i have all the proofs in written? What should i do?
