Csr — fraud job calls, harassing

I got ca on 23-aug-2019, about work from home, they give 10000 captch and 20dys time to finish that work with 90% accuracy, initially they dont ask and tell about money and penalty, i agree with work and i send my id proof, very next know about company fraud and call to company person they no respond, and i mail to their mail id and said that i want resign the job they ask the money for penalty other wise they can file case agaist to me. As mentioned people same thing done to me, but joining after one day i realize that company is the fake, and i mail to the company to resign the job but they tell pay 5100 penalty to close the agreement otherwise they legal way action against to me, so please tell the solution, the company cheating the people and playing with the need of the people.
