Yawn ..... just another scam, and part of the endless phone harassment that seems so much of the norm these days. There isn't anyone stopping such calls these days ... and so the scammers seem to be having a field day with it all.
I have gotten at least six robo-calls from this number and have reported all of them to donotcall.gov - unfortunately, the people making these calls are still in business.
I pick up and hang up immediately when I don't know the caller. That's what Caller ID is for. These insistent callers surely can't sell anything, can they?
