I have created multiple trial account to analyze Confluence and now they are showing up in my paid account admin console. There is no way I can delete those. So my question is will get charged for those trial accounts after expiration.
Welcome to Community! It's nice to meet you.
You can contact the Customer Advocates Team here, and they can help you out and ensure you only get charged for what you need.
