Excellent Data Solutions - — Threatening data entry worker

As mentioned in the other cases, similar situation also happened with one of my relative. he has completed all assignment of 1000 data entry with a great accuracy but he was told that his accuracy was not correct and received notice from a 'gmail id' saying legal notice to pay 3400. they have mentioned lot of legal terms for threatening. what i understood is -

1. if you see their doc, doc does not have any registered company identity, they are mailing from gmail and not from their company id, they neither have website

2. their icon on the doc is just an image taken from mobile and pasted.

3. now they are calling you repetitively, what-aping you, sending your recorded voice talk for threatening

4.All the complained are from October 15 to now. As the no. of complain increases. then they will not use this name. they will create new identity.

their business model is -
1. Take data assignment from companies, get it done by people with hope to pay
2. when the work is done, they will get money from company from which they have taken assignment
3. they will threaten the worker to pay or face legal action

it will be great if people at this forum can help in this situation. let me know if you need any document
