I got a call from this number today, did not answer but they left a voicemail - "Free extra benefits is you have both Medicare and Medicad, no more paying for ambulance trips, glasses and dental - press 2 now etc."  This is a robo call and I believe it to be a spoofed number.

A scam about medicare.

706-256-9390 is the FAX machine number posted on the website of the Columbus, GA Office  of the Dept of Family and Children's Services (DFCS) in Muscogee County.  FYI:  The main phone for that office is 706-321-2673.   I, too received a call from the FAX number but didn't answer it because it was out-of-area for me.  No message was left.

I suspect that a third party "hijacked" or masked the FAX number"  for the purpose of the Medicare promo that one respondent mentioned above .   (The name "Delta" came up among the hits that were returned got when I typed the phone number into Google.  However, Google also returned, at the top of the list, a link to the Columbus DFACS office, which is a Georgia State government website.

According  to the DFACs agency's website, some Medicare/Medicaid business is also handled through the same office.

Hope that helps to clear things up.  It just needs to be taken off the robo-operation.  I'm sure the State of Georgia doesn't know about it.
