Thank you for reaching out to the Community! It looks like if you have had that billing level it is because your active number of contacts did at one point go up above the 500 rate. We do apologize for any inconvenience this may have caused. I tried looking up your account through here but it brings up a canceled account. If you never uploaded more than 500 contacts into your account before can you please email social_support(at)constantcontact(dot) your correct username, the issue you are having, and a reference to this post. Thank you!
