appneta caller id - network mgmt company, did not pickup, likely selling stuff

This company has now called THREE times. Every time I tell them to never call me again yet they keep calling. This latest one said, "I personally have never called you before." Well, your company did and you are now breaking federal law by continuing to call me after me telling you to never call me again.

I own a website design company and this company called and tried to convince me that someone in my organization signed up for some web application program.  Since it's just me, I'm pretty sure I'm aware of what my "staff" does.  This is just another scam - feel free to ignore.

Network company. They have called twice a day for over a month now.
