I switched to a new phone and had trouble logging in to my account. When I did get logged in on the mobile app, there are no folders or files. I hadn't logged on to dropbox for a while, and I see in other posts that they will delete your files if you don't log in for a year - but that you'll get email notices. I don't have any notices and they are still charging me the monthly fee (last payment the first of October). Can you help? Is there a phone number I can call for help?
