I had a subscription with Dropbox and was trying to use Backup to save files on a couple of USB drives. I couldn't get this to work properly, despite lost of input from support, so I cancelled the subscription and got a refund. I still seem to have 140Gb of files in my account though. I thought I had deleted them but now I can't even see what they are.
I would like to go back to my free account with 2Gb but can't use that because of all the other files (that I don't need)
