Cancel a zoom meeting

Hello, 

I have learned today that Zoom support is useless. You open a ticket then they immediately close it with no comment. 

I have an end-user that no longer has access to an email but there was a reoccurring meeting that was set up with that account and has no way of canceling it. He keeps getting notifications for it and it still appears on his calander. Is there any way for him to have this meeting canceled or removed? 

Thank you in adavnced.
