Been receiving calls from this number since mid-January, and soon after from 404-965-5411 and 478-965-5411.  Caller ID is Name Not Found and they don't leave a message.  After not seeing any posts on 800Notes, I blocked my outgoing info and called the number, got a female voice recording that the number dialed is not a working number, and so added the numbers to my Call Block list.  Just wondering if anyone else has been receiving calls from these numbers...
