mmswm has the best answer. Several thousand dollars in fines will get them to take you off their list, and if that doesn't work then whoever's paying her to call can go sit in a jail cell.

If only Do Not Call worked!
I reported one company several times, keeping a log. Then I noticed that it was changing the phone number every few days to avoid the fines. I know it was the same because it was always Angela or Michelle with an important message about our credit card debt, which we haven't had for over 20 years, and then it was paid off in 2 months.
Now, I just don't answer any number I don't know, or at least flick the disconnect on my phone.
I've almost completely given up. One call, we mention we are on the Do Not Call and report, after that, we don't answer.
