If you're on the Webex Free plan, you don't have a Webex site administrator. Open a case for help with your account.
In Modern View, from the left navigation menu, select Support.
If you don’t see the above option on your Webex Events or Webex Training site, go to Support > Help > Contact Support.
For Webex Support, go to Support > Contact Us. Then scroll to the Contact Support section at the bottom of the page.
If the contact information for your site administrators is not available on your Webex site, then you can use your company's help desk to reach them.
