Sorry to hear about the issues you're having @Stuman!
If you have earned extra space for your account through referrals for example, then this storage doesn't expire as you mentioned. You should be able to see all the storage you've earned from your Plans page here.
Also, in terms of the deletions you mentioned, even if you are over your space limit Dropbox won't delete or remove any of your files and only syncing will be paused. You should still have full access to view and download entire folders via the web interface with the steps outlined here, as well as individual files.
To have a look into this further with you we would need to continue through our Support channel due to the sensitive info we would need to discuss. I was able to locate the open ticket you have with our Support team and I've followed up there so please just check your inbox when you have a moment and we can go from there.
I'll look forward to hearing from you - Thanks!
