they did not talk. they just hung up on me

Recorded message about a medical alert system for senior citizens that can be obtained at no charge - recommended by the AMA and AHA.  I selected option to be connected to an agent.  When I asked the agent for the company name, she hung up on me.  That should give you a pretty good indication of the integrity and validity of the call.  

Also- my number has been on the DO NOT CALL registry for 2 years - and this company clearly does not comply with the federal law.

since the fcc and the GOV wont do anything about these scam calls, the only thing to wish for is an itch they cannot reach to keep them busy;

Stop complaining and act.

The good news for you all... since nobody else has taken the time other than complain... I have filed a police criminal complaint against Level 3 and ultimately the marketing firm that uses the number.

This means that representatives of both companies will be hauled off to jail.

When you have an issue like these annoying calls, and you are registered on the do not call list... file a complaint with your local PD. My decision to criminalize the complaint is that several times someone was on the other end breathing heavily into my 11 year olds ear.

My next step is to see how the $10,000 fine per occurence can be involked

I didn't know you could do this.   I blocked this number from my phone, so they cannot call anymore.  I keep filing complaints on the "do not call" lists, but nothing happens.  These telemarkers hard so hard to stop, as they keep changing their phone numbers.

Hope it works for you
