I know the calls are frustrating, but this site has no affiliation with the company that is calling you and it is unlikely that posting in a forum will make them stop. What you need to do is register for the Do Not Call list (if you haven't already). It takes about 30 days to take effect.
If you're already registered, tell them not to call you again.
If not, give it the 30 days, and if they continue to call after you've asked them to stop, you can report them to
