I think most people who use 800notes know that the DNC Registry is pretty worthless for controlling calls like these. My phone has a 250-number blocking capacity and it's filling up fast.
Defenders of the DNC Registry--and there appear to be a few of them, likely government employees--say that telemarketing calls have fallen off sharply since the establishment of the registry. That's only true if you count large major legitimate businesses, who are the only ones who obey the law.
I receive more calls than ever, from solar energy salespeople, credit card "interest-lowerers", fake Microsoft technical people, lawn service companies, exterminators, sellers of fake extended warranties, phony IRS agents, mortgage brokers, air conditioning repair companies, and just about everyone else. Such calls are illegal but the FTC does nothing and never will do anything. Complaints just vanish without any action being taken by any government agency. It's pretty sickening, but that's government "efficiency" for us taxpayers.
I keep getting calls on my cell to "reduce my current interest rate" on my credit cards. I don't have an open credit card at the moment and the calls are routed through many different numbers and cities. I've asked to be removed from their list in the past, but this time I played along. I answered yes to their questions if I had more than $3000 in open balance w/higher than 10% int rate. They asked me to provide the card expiration date to verify they were speaking to the "right person"... I made up an expiration date of 11/2016--they said, "yes, that is what we are showing as well". Then they asked me to confirm the credit card number leaving off the first four digits. I said, "Well the first four digits are the same on most cards to identify the card type, so I'm not sure how that helps. Before I give you my card number, can you tell me the name of your company?"---and they had already disconnected the line. Scum like this need to be arrested as this has got to be part of a larger identity theft scam. When I called the number back, a recording asks you to press 1 if you'd like to be placed on a Do Not Call list. That's the only option and if you do nothing, it will say Thank you for calling and disconnect.
