A dropbox account was set up. I am not the administrator but the charges are debited to my credit card. The administrator has left the company. I want to cancel the subscription but it is linked to the former employee's email address. I cannot speak to/get help from Dropbox.
Otherwise, you'll need to contact Dropbox Support directly. 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.
