Global Publishing Work — Refund of deposit money and payment is not received yet.

Address:

New Delhi, Delhi, 110003

A mail has come from global publishing work, new delhi stating that, copy paste work and image to excel work. They asked me to pay a refundable deposit rs. 6000 and then they will give project to me. If i complete in time based on the error percentage payment amount will be reduced. Like this few terms and conditions were there. My first project is failed due to lack of accuracy and second also they said more errors are there. So i am asked to quit the project. So i quit the project and give settlement letter on september 28, 2015. From then i am asking for my refund. But still i have not received completely. On february month i have got rs. 3000. But remaining amount they are keep on saying that processing processing... Almost 237 emails i have sent them requesting my deposit amount. Really i felt very sad and frustrated in asking my own money which is a refundable deposit.
For my wife, her payment rs. 3750 is not yet paid by them. We are requesting them to pay the money. But they have not replied to my mail. Past three months i am keep on sending mails. They didnot provide any phone number also.. Really we are frustrated. We dont know how to get back our money from them. Kindly help us.
