Who called from 6784472819

Caller ID read:  "Out of Area"....left no message as these calls typically do.

Received a call no message, now blocked

Caller ID read "GA, USA". I'm nowhere near Georgia.

Received a call from this number on my cell phone, which I use for my business. Caller left no VM. Looked it up on different site and someone posted that they answered the call and the caller offered to reduce their credit card interest rates (poster claimed not to have any credit cards). Seems like either unwanted solicitation call or scam.

Had two missed calls when I called the number back, I got a message that this number is not a working number. It smells like a SCAM.
