Welcome to the Q&A Forum

Is that company does not have your legal permission you can take actions on that, I have the same issue on the past. First I tried to contact the source without any response at the end a court give us a permission to get those articles down using the hosting companies. Example if a site hosted on HostGator use our brand without our permission I can request Hostgator delete that content usually Hostgator deactivate the site  until the content is deleted by the owner
