These people keep harassing me, claiming that I know someone who I have never even heard about. I did a reverse phone look-up over the internet and found out that they are XO Communications. XO Communications is an Internet Networking Company. One of their customers are •Federal, state and local governments and agencies. I don't really understand Internet sh*t, but it seems to me that if you receive a phone call from this company, you should just tell them to f**k off and hang up the phone.
