Unwanted calls. no one leaves a message, when I try to return the call i get a hang up.

Keep getting calls from 646-513-4012. Upon a search using that number, it appears to be a New York number (spoofed I am certain) then below the New York number a BBB complaint...apparently some payday loan scam out of Florida. They want you to send $$$ up front for non existent loan. Glad I don't waste my time with unknown numbers . Never answer strange number, if truly important they will leave a message
