I'm hoping that my problem is a dupe account which "cause" deletion of all files for another user, although to my knowledge I have only one account. I'm having the same problem, I didn't use Dropbox Plus PAID plan for just over a year, and Dropbox deleted nearly all my 12,000 files. Support chat has been useless and frustrating, I OK them looking at my files to work on the issue, then hear nothing at all, and they close the file as Solved or Closed. Can someone here help me? I'm beyond frustrated and angry with this whole mess and lack of action or information from chat Harvey, Tiffany, etc.
