I was contacted by someone named harsh who took my signature and i sent him a copy of my aadhar card. On searching google i realised it's a fraud company and will not be working for them.
I have already sent them an email stating that i will not be working for them and the agreement states the amount can only be charged on innacurate work or if the work is not completed. I wanted to know if they will try to take any legal action against me as i have not taken the work yet
