8 calls in 7 days, I don't answer numbers I don't know, especially out of area code. Not once has this number left a message, if it was ligit I'd think they would leave a message.
Definately a scam. They somehow have a little personal information and then phish for more info such as credit card or bank numbers. They sound very legit. Beware. Why is there no option on 800notes for marking numbers as Scams?
