Viz Technology — Viz technology mailing me threaten me

Hey guys.
I also completed their work on time.I rechecked all the forms and forms were correct.But when I got QC report than what I found that they did not consider updated data.As when we filled first time so it's possible to do mistakes.But I recorrect them before submission.
Now they are threatning me via call and mail.
One thing is very clear don't pay single pie to them.
If want to teach them a lesson than contact me at ms.[protected]@gmail.com
We can unite against them and can save many other.
