Mike,  the caller is a fake debt collector calling from overseas,  usually coming from India or Pakistan. These calls have been a problem for several years.  The FBI and law enforcement are fully aware of them and where they are but they are untouchable by US Law Enforcement..  There are diplomatic protocol issues in trying to shut down and bring to justice foreign criminals  who are safely cuddled in the arms of an uncooperative government that considers them petty thieves and Americans free game for them.

'Has anyone reported this?'.

Of course!.   It has been reported hundreds of times,  even daily,  over the past couple of years.  But the plain facts are that people will just have to be more proactive in protecting themselves.  At this time,  the US law enforcement is stalemated by other governments.
