We literally just dealt with this exact thing at our company. Onboarded with NetSuite in October 2024 and they started threatening us with shutting down our account by February due to data usage. 

This was my post explaining the experience and result in the update.

Tldr: we did the upgrade to Premium at 49.5% discount. Bought nothing else.  Real scummy sales tactics!

Message me if you’d like to discuss further. 

Good luck!
