Nexgen Services — fraudulent

Hi i am avijit. I got a call from nexgen services for a form filling job of 650 forms in 6days for each form they will pay me 28 rupees with 90 percent accuracy. After that they told their terms and conditions that after completing the work they will deduct 4999 as their registration charge from my first salary. Then they signed me in a aggrement and said that they have sent me a i'd and password which i have to use to do my work and asked me when i am going to start the work. Today is my working day started and i didn't get my i'd and password and then i started investigation on this company and i found that this is a fraud company and in consumer complaints website their are many cases registered on this company. After that i realise i am in a mess. So guys plz help me out from this.
