Don't have access to the email I signed up with

Hi Debbie!

For individual accounts, Zoom requires access to the registered email for any account changes, including cancellation of a paid subscription. If you cannot access your email or sign in, and you’re unable to submit a support ticket, the only remaining option is to contact your payment provider (such as your credit card company or PayPal) to dispute or block future charges from Zoom. You can then create a new account with your new email address.

This is not an ideal solution, but it is the only way to prevent further billing for paid subscriptions if you cannot regain access to your account or email.
