Porspexa Tech — fraud

Sir this company contacted me and said that this is a part time job they are giving me i have to fill 500 forms and for each form i will get 30rs. Tgey said that after compliation they will deduct 4000 as a registration charge so i got convinced as i am a student and agree to start this as a part time job then they send me a mail in that mail there is a agreement paper and they take my sign online, there is a stamp paper attached with that mail of rs 100 so i agreed and signed that agreement then they send me my user id and password for the login and filling the 500 forms so i started this from 6/4/19 and i have to submit this on 10/4/19 in 4 day i have to fill 500 forms. What made me realise that its a fake company is that there form is of the other country so that i have to face problem in filling the form nd then i have to pay them 4000 rs as written in the agreement that if i will not complete my work in the given time i have to pay 4000 to them and will not get the salary so it hits me hard after seeing the forms and then i googled it and what i was thinking is correct this company is fake donung frauds and i am very tensed what to do now i am still filling the form as i have signed the agreement but i dont want to continue this i want to stop this but i cant because i dont know what to do how to do thats why i am completing their work but please help me with this i am extremly worried i am a student please help me.
