Forever 21 - DO NOT SIGN UP FOR EMAIL LIST

I signed up for the Forever 21 mailing list, and now I dont want to receive emails anymore. I tried to contact them via a contact form on their website multiple times telling them to stop emailing me and to take me off their list. However, they wont and the emails keep coming. They have NO customer service, no email address, nothing. Also the link at the bottom of the email to "opt out" doesnt even work. This company SUCKS!
