Anyone else seeing mailboxes with Exchange Online 2 showing they now have 150gb?

My apologies if I am misunderstanding on the mailbox limits you outlined.  FOR THE PAST 3 YEARS, we have 15 users with Microsoft Business Standard with 100GB of email storage space and 11 with Microsoft Business Premium with 100GB of email storage.   I have 1 Business Standard with Exchange On-line Plan2, and 1 with Exchange On-line Plan2.  Both now showing 150GB of usable mailbox storage.   Both users for several years, leading up to September 18, 2026 showed over 100GB of mail in their mailboxes and had no problems sending or receiving email, ever.  THEN ALL OF THE SUDDEN on 9/18/2026, these 2 users with Plan 2 are no longer able to receive any email and it now shows their mailbox is full Even though checking active users details about mail for both of these users shows 150GB storage.  In investigating further, in the exchange area of the admin portal, checking mailboxes indeed both of these 2 USERS ONLY SHOW 100GB, the exact same as all my other users who are not paying for PLAN 2.  HOW DO I REPORT this to Microsoft?
