I received a call from 1-407-000-6937 and when I answered there was no one on the other line. I would like to know how they even got my number to make the call. There is no "000" prefix that I am aware of, so my advice to others is just don't answer the phone if this number appears.
They have called me several times. When I tell them I am on the DNC, they rudely hang up. All I can ask is where does the law step in. I am sick of their calls!
