Before 7-8 days a girl called me her name was priya sharma and she offered me a home based typing work abd she told me that there will be 700 form for 7 days and per form worth is 35 rs and for 700 forms they will pay me 24500 rs and then i agreed to work but after taking work from them i got to know about there fraud complaint then i said to that girl and she said me to talk on there customer care number([protected]/[protected]) then i call to these numbers but they were not picking up the calls, for 7-8 times i called them, after this i talked to that girl if I don't get any information about this complaint then i won't do your work, then that girl didn't rply me and she also didn't recieve my call.
Then i stopped that work after doing 21 pages.
But today i got a mail from [protected]@outlook.in that i will have to pay 6000 rs and if I don't pay them they will take a legal action against me in court. Now what to do?
