Hello. My account shows that it is fully used (>100%) with no free space for any new files or folders.
I found these two support articles which show that support needs to run a script to fix the issue:
https://support.box.com/hc/en-us/articles/360043695334-Storage-Usage-Or-File-Count-In-My-Account-Is-Incorrect 
https://support.box.com/hc/en-us/community/posts/13057753420435-Need-to-run-the-script-on-my-box-account-to-reset-the-correct-storage-size

Can you fix the incorrect usage problem (by running the script or whatever else is required) and let me know please (the login id is as@a1v.me)?

Thanks in advance,
Adit Sood
