Kamara Techno — demanding money without reason

Sir,
In the pandemic situation i lost my job and was looking for some income and applied for work from home on quikr jobs. I got a call from a person named dinesh he offered me to fill online forms and they will pay me rs. 40 for per form, they got a agreement signed after that they allotted me work but 2 days later i got sick and got high temperature, i informed them that i am not well and can not complete the work, now they are demanding money for not completing the work, and harassing me on phone. Kindly take action against them.
