Daily Spam Calls

For the past few months, I have been receiving constant spam calls from MiWay Insurance. I have told them 3 times verbally to remove my number from their calling list. I still am receiving daily calls from them, despite my requests. I messaged their Facebook page with my number telling them to remove it, to which they responded saying it was removed. Now I still received another call this morning. The thing is, I have never done business with this company. I have never once provided any of my details to MiWay. I asked where they got my number from, no response. I have now requested 5 times to be removed from their calling list, and yet I still receive daily calls. I am now certain that they are trading personal information on databases. I never subscribed or provided my details, and even after numerous requests to be removed, I am still receiving these constant calls.
