You are receiving billing emails with invoices ONLY if you have created your own web conference account OR someone in your organization has set up a user account for you in our system and has specifically designated you as a Billing Contact.
If you believe you should not be the billing contact, please contact the person in your organization in charge of your web conference service and ask him/her to go to the "Manage Users" section of the Admin Page and remove you as a Billing Contact.
We do not send any spam emails and apologize if you are getting the invoice as a mistake.
Thank you for your cooperation.
