Crossway Technology — harassment and blackmail

As it was my summer vacation and i had nothing to do so i thought of doing some freelancing and earning some extra pocket money. So i applied to this company and i got a call from one virat saxsena and he said that the company was geniune and it can be trusted and as they provided me with legal bond paper i thought that it is genuine and i said i'm interested
But later when i couldn't find any website of the company i mailed them regarding this and i didn't get and reply
But after a month one manpreet kaur called me and said that i have to pay utility charges and i didn't complete the work as it was my fault i paid the money but even after that they kept calling and were asking for more money and said that they would file a case against me if i won't pay
I qas scared and paid whatever was asked
Again after a month or so i got a call from kapil adhikari saying that i have to pay to close my case
But now i don't know what to do as they are asking me. For more money

This is a mental torture and is effecting my studies and those people know that i'm a student and still they looted me without even thinking about how it'll effect me, idk how can someone be so inhuman i just hope karma hit them so bad that they regret doing such inhuman thing to kids who cry in front of them.

And idk even if this site is real or fake
