This is a company which re-sells AT&T service. They want to sign you up for AT&T Internet. "Your number has been selected to receive AT&T Internet Service."
You could try to tell them you are recording the call and ask if they agree to that. If they say yes, have the caller identify himself again, then tell them that you are on the DO NOT CALL list and you wish to be removed from their call list, and tell them that if they call again you will report them and they will be subject to paying you $500. Then hang up. Do not answer "yes" to anything he says.
Hey I'm not trying to sound rude but I'm just giving you a heads up. I'm a telemarketer. The National Do Not Call list doesn't except you from telemarketing calls. If you hold an existing business relationship with a company the legislature who created the list has entitled us to contact you about offers that you may want to know about. dnc list really is no help. Just a heads up. So in all reality unless you ask to be put on the company's dnc list, they can't owe you any money. Just a heads up. :P and by the way, we hate our job as much as you do.
