I opened a Trello account because my professor asked me and my 5 other group members to use it for our group project. When I signed up, I said I wanted the free version. However, on April 15,2020 I got charged $638.95 which is ridiculous. What am I supposed to get a refund. I filed my complaint through Atlassian Support and they sent me an email confirming they're on it, but I haven't heard back since this morning. Can someone help me out cause I'm a college student on a low budget and $638.95 is money I've worked hard to see go.
