The same thing exactly happened to me today on 5/30/14

I also received a call from this number. They asked for my mother by name and when I said she was asleep. They asked if she was laid up drunk on the moonshine he and Danny brought her. Then he asked if her last name was Robertson and when I said no then he said he had the wrong number and hung up. It was a man's voice. He called at 8:25pm EST on 12/11/2013.

The date of my call was at 8:25pm EST 12/11/2013.
