Where can I go to stop spam from a particular source
I am receiving numerous emails from a professional event organizer company advertising one of their events. I replied indicated no interest, then requested not to send further emails, then shared my irritation to the sender IDs, but to no avail. Then I wrote to the managing director who told me they can't stop sending spam emails and I should delete them. I again wrote for them to find a way as the emails impinge on my busy schedule and cause nuisance. But even after 2-3 exchanges the MD also wrote a very rude mail saying he doesn't have time for addressing my request and he cannot make sure I don't get these emails and asked me to do whatever I wanted or I could. Can you guide me if there is a legal recourse I can take?
