EFAX.com account suspended and still receiving demo documents.

My email is fritz@buckheadcs.com and I am unable to stop receiving these emails.

I signed up 2 months ago as a possible solution for dealing with paperwork.....I found paper worked equally as well for my applications and now I receive a request to sign demo documents weekly. There is no unsubscribe button. When I follow the links in the email it says account suspended.

EDIT:I just tried emailing "stop" to webmaster and postmaster@efax.com, both bounced
