Onlineworksjob Dindoli Surat — fraud form filling job

Address: 902/A Emporio Complex dindoli Surat

On 9 march 2020 i got a call from the company. A guy addressing him as nikhil called me nd offered me 28, 000 for 800 forms nd they took my digital signatures before mailing me the agreement. However, he was so fluent on the call that i can't even understand that they are going charge 4000 as penalty when i am unable to submit the forms. When i realized that i can't do this in 7 days i called him nd he told me that i have to give rs. 1000 for increasing my working day which wasn't mention in the agreement nor on the call. Later i have checked company details there is no toll free number of the company nd all the reviews are against the company. They are mentally harassing me and claiming that a case has been registered on my name. Please help me out. I'm just a student nd 19 years old
