Savya Bpo Services — Wrong accuracy report given with the consent of fraud

I got the task of filling 1000 forms in 10 days with the accuracy of 90%.
I did the same, completed the task within the time. I did my best and submitted the work after checking all the forms twice because I didn't want to have any default from my end or lack.
3 days later I got the Quality report with the accuracy 834/1000, which is not possible because I checked it twice before submitting finally.
The same day I called their Helpline and legal advisor but both of them were switched off. Later, I called the executive who was first busy then we talked and she told me to call now that, now I will be able to talk, and it happened so.
The advisor asked me to pay the registration amount of Rs.3400 within the 6hrs or I will be imposed by section 17 (ICA), If I don't pay they will go for IPC 420.
Even I got the WhatsApp text from him for transfer details for the same and he messaged ( see how we spoil your future
you don't pay any charges ).
I am not going to pay anything, I know I didn't fill any form wrong, or in any case 10-11 wrong fillings can be agreed but how is it possible to get 166 wrong forms after checking them all twice.
All these means the Fraud Act.
Just don't go for them, they are all liars, trying to get the money in the name of registration amount.
