It's a scam, When I get those kind of calls I answer the phone as Sheriff's Department fraud division how may I direct your call. That well cut down on those scam calls a lot. It has me.
You should get something in the mail first before they call. With an official Social Security Return address listed on it. An 866 number is like an 800 number. If you are still unsure. I would go to the social security office in person. I got rhe came call as well. It is fake and dont give them any info. Always hang up.
