Who is this number calling

They called.  A man with accent, said my Doctor told him to call.  (5/16/2017 @  4:22 PM)
Scam for sure!!  Hang up.  I told him my Dr. did not tell him to call.  I had just. gone to the Dr.  When I asked where he was
calling from, he hung up.  It's a medicare scam.  Don't answer these call.

He lied.  Said Dr. told him to call me.  I said Dr did not because I had just went today.  I go back Friday to Dr.  He has an accent,
and hung up when I ask him where he was calling from.
