I'm abeesh,
I had received 56 pages of data entry work from static info and gave the agent number and his name is gowtham. And they asked to complete the work within 15 days and i've completed work. After that they gave accuracy rate 92.22%. And they asked me to pay rs. 5681 as security charge and refund along with your salary. I've paid that amount after that they again asked me to pay rs. 1500 as paypal account and said your salary will credit within one hour and i've also paid that amount also. After that agent didn't attend my call and also blocked my number. I totally lost my amount. What should i do now? Please help me
