Our account has not reached the quota yet

Hey I'm the IT admin for this company. I'm unfamiliar with this system but they tell me that they cannot upload and received emails saying they have reached their quota.

But according to their account (see screenshot) it's not full.

Hello,

We apologize for the inconvenience. It seems to have been mistakenly suspended by our system due to a recent account change. Upon checking, I have found that your account is fine. It is now active.
