The trick to making these calls stop is to convince them that they are wasting their time and resources to call you. This is very difficult to do since the resources that they waste are small and the reward of scamming you out of your money is so great. I have found a way however. You must proceed until you get to a live person. Then tell that person in the most forceful, obscene fashion that you can that they should go engage in intercourse with themselves and then call you back to report the results. This conveys the idea that subsequent calls will not be productive and they remove your number from the list more certainly than any other way that I have found. It also is very good for relieving the frustration that they have caused you to feel.
Perversely, this is also what is best for them since it prevents them from wasting time trying to wheedle you into changing your mind.
Try it, you'll like it.

Same story. However, check with your cell phone company and see if you can block the number... We use Sprint and they have a block feature that you can block any number from calling you. AT&T used to block numbers of known culprits if you call them and report it they not only block it from your cell phone number, but tag it to show up as a scal whenever they call someone on the AT&T System. Verizon, when we used their "cell service" had no block options at that time.
