they called my phone just now as well, but left no voicemail. attempted to call number back and asked for my number to be removed and it said it was publishers clearing house.
You have to put your number on the national do not call registery or else they will keep calling. They don't have an opt out option. If they say they do they will remove you from one number and call from a different one. Even cell phones are listed now unless you register online with the national do not call list. Hope this helps you all!
