I answered because "THATS WHY I HAVE A PHONE" but mostly because I'm expecting a call from my daughter in the Air Force, being deployed over seas I never know what my caller ID will be. Anyway, they asked if I voted in the last election and I told them it was none of their business, they asked me to spell my very simple name, I also told them if they knew me they would know how to spell my name and hung up. It's so sad that I can't use my own phone without being blasted with call from God knows who! I hardly ever got a call until I placed my name on the so-called do not call list...!!!
The DNC list is for legit companies to use for their cold-call marketing. If you are on the list, they delete your number. Exempt from the DNC list are charities and political callers. These scammers don't follow the rules and the number you see on your Caller ID is most likely not the number they're really calling from. Most of the calls originate outside the US and they will not only never be caught, they are outside the jurisdiction to be prosecuted. It's sad, but true...
