I received two calls identical this morning. This is a SCAM. Please see the link http://oig.ssa.gov/newsroom/news-releases/march2-advisory. DO NOT CALL THIS NUMBER!
Same for me, saying SSN had been suspended. I called the number so I could prank them back, and it said, "The google subscriber you have called is not available, please leave a message" The scammers need more numbers if they don't want the Google Voice default voice mail message to blow their cover!
