Corevestor Glob Enterprise — attention!! fraud company

Address:

Hazaribagh, Jharkhand, 825301

I gave them a work of 1200 forms. They promised me for accuracy of 100% which i agreed to. Before work, i asked them if i could pay half of the amount before the work and half after getting my salary from my employers. They agreed to it. However, later while i paid the first half of the money, they asked for the other half too. I reminded them what they agreed to. But they blackmailed me saying "send us the other half of the money or we will not logout form our device". I had to pay them. But had a relief that atleast the work was done, and i was finally going to be paid. But that didn't happen. The accuracy test failed and when i called them back all they said that they don't know about anything. Such fraudsters they were.
