Really Annoyed at AT&T

[stickmaker]

Just as I was finishing my previous post, the phone rang. This is the third time in a week AT&T has called to offer me DSL service. This time the caller flat-out lied to me. "We've never offered this service in your area before..." "I had it before, and didn't like it." "...and we're offering a special deal."

I'm on the national Do Not Call list, but this apparently doesn't apply to "legitimate" businesses. How do I get them to stop calling, since telling them to stop isn't working?!

Seriously, I am just about ready to switch services.
