This number called an hour ago unknown, no message do not want calls from this number

called 12:20 on 3/18/2014
caller had odd accent
office sounds in background
asked for "Alfreda Hamilton"
Told him no such person here and terminated call.

Called me but I didn't answer, probable a work from home BS

A guy with a strange accent, sounded like he was calling from a room full of people making calls in the background.  Claims to be from American Health Care systems.  Not sure what he wanted, but hung up when I asked to be taken off the calling list.

I have been receiving calls from 2 numbers 011 206 801 1722 and US 786-607-7448 with a woman with a deep accent telling me she was from the American Medical blah blah blah and I had a bladder mesh surgery.  I told her that this is that telephone scam and she was not to call my phone again.  I received several more calls and I still blocked the number from my cell phone.  

Another scam to try to get personal information from you.  Just hang up or answer the phone "FBI hotline"  - that works.
