terrible customer support (non-existent), when we had to upgrade the webinar feature to 1000 attendees, there was no feature to select "no auto-renew" as we only need to upgrade for 1 month, then tried several times to reach out the support to downgrade the option back to the original plan I signed up, I had a reply from someone in support team and promised the downgrade has been done and there won't be new charge for my upgrade plan. little did I know, the support guy did NOTHING to cancel my add-on request, subsequently so I was charged AUD$496.99. I emailed their support team (they use zendesk) several times, to this date (after 2 weeks from my first request of refund), still NO reply. Terrible service, DO NOT USE ZOOM!. will switch all my future webinars to another provider. They don't simply support you when there's an issue.
