Hey @KathyStar1, unfortunately we can't share our direct emails, but here's what you can do:
You can 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 do, feel free to send me the ticket number reference, in order for me to locate it on my end.
Let me know more!
