Where can I make a report on how I was treated on a MongoDB Webinar?

I was on a Webinar today for Advanced Querying: Beyond the Basics and my question was getting ignored for over 20 minutes in the Q&A panel, meanwhile everyone else was getting replied to within 2-5 minutes. When I brought this up, I was just kicked from the Webinar without any warning. I don’t appreciate being targeted and harassed liked that and would like to issue a formal complaint about this. This is not right and they shouldn’t be treating customers like this.
