I am a student and i just registered for this company because i wanted to earn a little money to help my parents during lockdown and only after accepting the confirmation call i found out it was fraud. I contacted them to cancel the contract and they messaged me back and are asking for 6700rs as a cancellation fee. I'm scared that they will threaten to serve me with a legal notice since there is an agreement even though it doesn't have my signature on it. Please help me resolve this issue
