I got a call from askme solution for online form filling part time job, a women explained me about the job and they send me the agreement which i signed but didnot tell me about the policy and they provide a username and password and told me that i have to fill 1500 forms from which 1400 should be correct, i have not done the workand now they asked that i have to pay 7000rs because my qc is failed.
after 1 month i received a message from HP-LEGALC WITH ID NO.
What should i do should i pay them money or file case against the company.
And his advocate is calling me and forced to pay the amount.
What should i do?
