I never answer unknown calls. I will call the number back from work land line and invariably I get the answer I am looking for - it's a robo answer that says 'press one to be removed.' No identification. This is a sure sign that it is not a legit business. And as usual I come here next and get the confirmation I am looking for. DO NOT PICK UP numbers you do not recognize - these callers want to separate you from your money and or your personal information.
Called this number back. Recorded female voice states 'Press 9 if you wish to be placed on our Do Not Call list'. When you press '9', voice states that it will be up to 72 hours before you are removed. So I assume this is some phishing / telemarketer scam number. Hopefully, they won't call back.
