recieved a threating email saying how will be charged  lawsuit  all rights reserved to inform the fbi,ftc.my employer and attorney fees.  and other charges.

Indian debt scammer.  Accent so strong you can cut it with a knife.  Total scam.  Ignore e-mails from these [***]. Do not return their calls.  They seem to be using area code 206 for their garden variety scams.

Total scam. Says you're being sued.  Sends emails telling you that and now calls.  Heavy accent, many verbal errors.  Email is full of errors.

File a complaint with IC3, the cyber crimes division of the FBI, you can attach the emails to your complaint.

For Extortion Scam Operations,  File reports with the FBI, your state attorney general and Department Of Justice,CFB,FTC & FCC..
