Locked outside my account

Allo everyone,

I changed my account email from 'email1' to 'email2' not knowing 'email2' was actually not designed to be used in Zoom. As i can't connect to my account with 'email2' , i can't neither switch back to 'email1' nor get my host ID to call technical support.  

How can regain access to my account or get my host ID to get help?

The only thing i have right now is an invoice that states my Zoom account number.

Thanks and have a nice day,

Lucie
