You need to contact Support directly, not through the app.
Visit the Support page while you're NOT signed in to a Dropbox account, including these forums, and you'll see an option for Billing issues. It's best to use an Incognito or Private browsing session to make sure you're not signed in. Once you've filled out the information and submitted it, reply back here with your ticket number.
