Need to change email address on my account

I recently changed my email address and no longer have access to the old one that is attached to my account.  When I tried to edit my profile to update to the new email, it told me that a confirmation email was sent to my old address... the one that I cannot open.  I tried to contact Support but hit a brick wall since I am not a Premium user.

The problem first became evident when I was hosting a meeting the other day and it timed out unexpectedly at 40 minutes.  I can only guess that notices of the expiration of my contract had been sent to the old address.

Since I cannot talk to a living person at Zoom, I am at a loss for how to fix this problem.
