Phone rings and when I answer, no one is on the other end. It is silent for several seconds and then I hear clicks of the line disconnecting. Annoying when I drop what I am doing to answer their calls. When I do get a live person, I have made a game of trying to waste as much of their time as possible without giving them any info. (Although they have my number) I have repeatedly asked them to remove me from their list. They ignore the "do not call" listings.
