Who called from 9844458511

Received a call from 984-445-8511.  Oriental man named "John" claimed something was wrong with my computer.  
Told him nothing was wrong with my computer but something would be wrong with his if he didn't remove my number from it.  
He hung up immediately.
Do these people have anything better to do?

5:00am! Really? From North Carolina?

Told this women we didn't have a computer and she immediately hung up

Received call this morning and ask that my number be removed from the list.  A male with a strong foreign accent said that removing the number could not be done and that they would keep calling about a malicious virus that supposed is on my computer.

Same an Indian lady said she is from Windows there is an error from my computer,I just hung up on her!
