Continuously sending Spam

Even though I have not subscribed to their internet marketing site, I receive regular spam e-mails from [URL Removed] I tried to un-subscribe numerous times. I also tried to log into the site, but received an error message that the e-mail is not registered with them.<br> I then sent an e-mail from their contact page complaining about continuously receiving spam email from them. In the mail, I stated that I would contact Hellopeter.com with a complaint, should they continue to send these unsolicited e-mails to me.<br> If there is someone who could direct me to an effective spam reporting site, I would really appreciate your input.
