Exactly the same thing happened to me as well. Called pretended to just realize that I am on the no call list and then proceeded with a very pushy sales pitch. And even when I stated that I was not interested they still kept going. I had to hang up just to get them off the phone. Someone needs to do something about this. What is the point in putting my number on the do not call list if companies like this ignore the law?

They called me on Dec 05 at 1936 and admitted I was on the do not call list and apologized for calling ...but still proceeded to try to sell me their duct-cleaning services.
