Scamming in the name of Part time Work

I recently visited a website earndigital[dot]in. After sending query they sent me registration link. I thought it is primary to get registered. i gone through some steps and finally done registration. They sent me a agreement and all. After that got a call from one of the person to give instructions, where he mentioned that if not completed work properly or with below 90% accuracy then I have to pay them in return. I thought it is inappropriate and asked him to deactivate my account but he told that for that also I have to pay an amount. So, here by complaining about them.
