I received the same call as Mary

Unknown number.   I never answer these calls.  They did leave a voice mail.   IRS scam with a heavy Indian accent and poor English..  Requested a call-back to same number.   Not happening.   Added to my block list.

Numerous calls from 917-651-0197 pretending to be an officer of the IRS..  They leave a voice mail and it sounds like they are reading a script in a warehouse.   IRS scam with a heavy Asian accent and poor English.. Stating that our property is under Federal investigation and to call back immediately for more details. Requested a call-back to same number. Not happening.   Added to my block list.
