It seems that you may have encountered a change in your billing structure for your Microsoft 365 subscription. According to the information available, if you are receiving additional charges after activating a benefit or making changes to your billing frequency, this could be the reason for the unexpected charges.
Here are some possible explanations:
- Changing Billing Frequency: If you changed your billing frequency from annual to monthly, this could lead to additional charges. The default billing cycle is monthly, and switching to it would cancel the annual benefit and start charging your credit card.
- Invoice Changes: If there were changes in the billing periods or if you received two invoices for the same subscription in one month, this could also explain the additional charges. This typically happens when the billing structure is updated, and you may receive invoices for different service periods.
- Additional Subscriptions or Services: If you have added any additional licenses or services to your subscription, this could also result in extra charges.
To clarify the specific reason for these charges, you may want to check your billing history or contact Microsoft 365 support for detailed assistance regarding your account and billing changes.
