Scam caller - claims to be the IRS and calling about a Warrant.

My 87 year old mother got this so called "IRS" phone call saying she was being sued.  She was freaked out and saved the message for me to listen to.  I told her it was a scam and DO NOT call the phone number.  BTW her phone numbers are on the DNC list.  What good does that do?!

Did you actually think about that before you posted "BTW her phone numbers are on the DNC list.  What good does that do?!"?
Foreign criminals called her ignoring the DNC law so that they could steal money from her, again ignore laws against stealing, impersonating a federal officer, etc.  Tell me something.  If you locked the door and someone broke the lock and entered into your home, and stole your TV, would you blame the lock?

Claimed to be from the Federal Bureau to alert me about a computer hack.  phone number 360-200-0899 foreign accent
