How to get rid of Telemarketers and debt collectors

I had one insurance company calling repeatedly saying that they were responding to my online request for insurance. I never went online and couldn't get them to stop....4-8 times a day, every day of the week. I finally blocked their number with Verizon. Even the Do Not Call Registry doesn't work.

I also like the companies that call offering loans. I tell them I lost my job, had to declare bankruptcy and don't plan on paying them, so free money is always appreciated. They normally stop calling pretty quickly.
