Can't log in - 2FA not working

I have 2FA enabled on Zoom Pro and since upgrading phones the 2FA is no longer working.

I can not log into the account in order to disable it. I can not use Apple or FB because this account is set up using my work email. 

I can not even call support because they are asking for a personal meeting ID which I cannot see without logging in. 

I am going around in circles - please HELP!
