I have been getting a call from 520-000-000000 too. I have not answered it and they do not leave a voice message. They have called me twice this week. I am getting really annoyed by it. I wish I knew why this is happening.

They keep asking for whorehey, and then when i say "i know no whorehey," or "u have the wrong number" they cuss me out.
