Data Info Services — asking money

Hello sir this is veeresh from andhra pradesh . Sir one of the company data info services(automobiledataentry) has made a cal to me and they said about the job of data entry and I accepted to do.. But they just sent me the agreement to my mail and Instantly they made a cal to accept that and click on the verify and then asked to send msg like I will take the work to thiers mail. Without reading any instructions.. Forcebly made all those... And provided work.. They said that you have to do 1000 forms within the 7 days.. Otherwise you have to pay 4000 if the accuracy doesn't reaches 90% .. Finally I tried to do but after some time I realized that they are doing some fraud and the person who made a cal to me.. Was blocked me in whatsApp.. I asked her to cancel my work and she was blpcked and again I sent message to their mail and they said that you have to pay 1500 to cancel my work.. But I said no.. After they said otherwise the work will continue if you doesn't pay.. After that you have to pay total of 4000 .. Please take strong action against them... I am poor person.. I can't bare like this
