Box says that my storage is full

Same here!

Same problem I have been facing since I purchased a business plan a week ago.
I am planning to migrate to Dropbox.
Very bad service provided by BOX

Hi Rafi,

Welcome to Box Community and glad to help!

Great news! I went ahead and fixed your storage count. To verify this, log in to box.com> Account Settings> Storage Used.

In the future, if you experience incorrect storage, please let us know in this forum.

Hope it works!
