What else can I do?

I just got awakened from a much needed nap this afternoon by an unwanted phone call from someone I don’t know and offering a service I don’t want. I get 1-3 or more of these calls every day and I have registered with the “Do Not Call List” three times! What else can I do? My friends have the same problem, so obviously they can’t help me. Today’s 2nd call was from, it sounded like, a very young handsome(?) man with a very nice voice who wanted to remodel my house. Since I didn’t want that service I just hung up. But then I got to thinking. Most of the previous calls were from women with accents. Some accents were so thick I could barely understand them. (Just got my 3rd call of the day while I was typing this. This caller had a very strong accent.) They have my name, they use it to get my attention. I have to ask who’s calling since it could be someone who I already know. My curiosity kicked in. I think it is unfortunate that these people cannot get a better job. I hope they are being paid minimum wage at least. I hope they are paid for every call, not just the ones who accept the offer of service. Surely the nice young man today should be able to get a better job. But I can’t continue to receive their calls. I want them to stop. They interrupt my sleep, my meals, and my work. I just got my 4th call of the day at 9:15 tonight! Anybody got any good ideas?
