- Observed behavior
- An unrecognized recurring charge for a Microsoft subscription appears on the user's AMEX account.

Contact Microsoft Support for Billing Investigation
Because billing inquiries require access to private account information, you must contact Microsoft Support directly to locate the subscription, cancel it, and request a refund.
Subscription and payment issues involve highly sensitive financial data. Microsoft cannot investigate or resolve these unauthorized charges in public community forums.
By speaking directly with a billing advocate via chat or phone, they can securely look up the transaction ID from your AMEX statement and stop further billing.
Navigate to the official Microsoft Support website in your web browser.
Click on 'Contact Support'. If you have a Microsoft account, sign in to expedite the process.
Choose 'Microsoft 365 and Office' or the billing category from the available product list.
Select the option for chat or phone support. Provide the agent with the charge details from your AMEX statement so they can identify and cancel the trial subscription.

Avoid Unexpected Subscription Fees with WPS Office
If you want to avoid confusing trial conversions and unexpected recurring credit card charges, consider switching to WPS Office. It provides a robust, lightweight, and completely free alternative to Microsoft Office without the hidden subscription fees.

- 3. Start Creating: Launch WPS Office to immediately start opening, editing, and creating documents without entering payment information.

Frequently Asked Questions
Why am I being charged for a Microsoft 14-Day Trial?
Microsoft often requires a valid payment method to activate a free trial. If the trial is not manually canceled before the 14-day period ends, it automatically converts into a paid, recurring subscription, which triggers a charge on your card.
Can I dispute the unrecognized Microsoft charge directly with American Express?
Yes. If Microsoft is unable to locate the account associated with the charge or refuses to issue a refund for an unauthorized transaction, you can contact American Express customer service to dispute the charge as fraudulent and block future Microsoft billing.
How do I check my own Microsoft account for active subscriptions?
Log into your Microsoft account online, navigate to the 'Services & subscriptions' dashboard, and review the list to see if you accidentally left a free trial active.
Is it safe to ask for billing help on public Microsoft community forums?
No. Billing and subscription issues involve private financial data. You should never post transaction IDs, card numbers, or personal emails on public forums. Always use the official Microsoft Contact Support portal.
