Options to retrieve my data

Hi folks. I have a legacy unlimited storage account and I recently learned that in January '24, Box started monitoring and enforcing 1TiB/user/month bandwidth limitations. I currently have some 12 TiB of personal/business media backups that I would like to download from Box so that I can decide if the new limitations will work for me going forward. When I tried to download some of it I hit the limit and now must wait until the new calendar month to download more. I shudder at the thought of having to retrieve the rest of it over the course of a year! But it gets worse: if I use the bandwidth to download, I obviously lose my primary backup site as I won't have any bandwidth left to upload in the meantime (even if I trim my backup sizes way down).

I hope there is some way to do this and/or to get a one-time exception so I can have all my backup data in my posession without waiting a year! Thanks for any help you can provide.
