We got a call from this number again today at 9:56 am, and it was blocked by our call blocker. The caller ID was still GREENVILLE SC. Please see my post of 11 Jun 2015. Note: I am not the same Ken who posted on 16 Jun 2015.
This number called consistently for weeks straight. Upon answering, they would hang up right away. In attempts to call back the number, whoever answered would hang up immediately.
This is a fraud or spammer who calls continually. If you see this number calling you, IGNORE IT.
