Storage isn't changing

I only have around 4.9GB of files in my box but it is showing 40GB. I deleted everything in my trash as well and it isn't fixing itself! I see a bunch of posts with this problem. Is there a way I can do this without needing support to correct it? Kind of a problem when I'm uploading files here on the daily and it won't upload because of a false storage full problem. Please please please fix or I'll have to use a different cloud storage.
