Frequently Asked Questions
Why am I being charged $179 by Microsoft?
A $179 charge typically corresponds to a specific Microsoft business or premium subscription tier. If you do not have a business account, this could be a sign of an unauthorized subscription, a forgotten trial conversion, or a scam, and you should contact Microsoft support immediately.
Can I get a refund for unauthorized Microsoft 365 charges?
Yes, if the charges are proven to be unauthorized or fraudulent, Microsoft billing support can often process a refund. If they cannot locate the charge, your credit card issuer can reverse it via a chargeback.
How do I stop Microsoft from charging my card every month?
To stop recurring charges, you need to log into the Microsoft account associated with the subscription, navigate to 'Services & subscriptions', and turn off recurring billing. If you don't know the account, you must contact Microsoft support or your bank to block the merchant.
