Received call repeatedly, jjust curious who it is.

Don't know why this number has been calling me over and over again and never leaves a message.
Starting me bug me that I am going to file a complaint with the national do not call registry.

It's a company called "Vertical Search Works" and they trying to sell you on advertising with their ad network.  Similar to Google AdWords, but supposedly more focused where they position you within certain verticals.

I'm not sure, but it may be an agency doing the calling work for them. I talked with them a few weeks ago, set up a web meeting, and then told them that we'd get back with them.  After a few weeks, they called me back on a Friday eve at 6:30pm.  Shouldn't these people be at happy hour?

Stop these unsolicited calls. Caller would not identify herself and would not let me take a message.

This number has called several times and not left a message.
