I've received numerous calls from this number. Everytime I pick up, it's a recording that want's me to take a survey. It's extremely annoying! I'm trying to find out how to report it.

Called while I was sleeping, told me I had filled out a form to receive information about online classes (untrue) and when I asked where they were calling from, the line was silent.

Verizon Wireless survey for CS follow up.

On-line says this is Western Steel Building in Littlefield, TX. They called my office, I answered and they hung up.

This is an intentional hang-up call used by a process server to find out if anyone is home. If you answer it hangs up. Within two hours they are at your house, catch you at home and serve you with photo radar or other court docs. If you call the number back it has a recording that says "Thank-you" and immediately ends the call. I assume its an autodialer used to find out if people are home or not. This is dangerous. What's next? Burglary?
