Why I have been charged without buying anything?

You can check http://commerce.microsoft.com to see if it shows what the charges are for. You'll want to contact support and speak to billing for any further assistance. 1-800-4my-xbox if you're in the US/Canada
or http://support.xbox.com/contact-us

Hi Nevwah!

Sorry to hear about that. Could you please check your account order history on https://account.microsoft.com/billing/orders/ if you could see a recent order with that same amount? If not, it's possible that it may be on a different account.

You may want to check from your family members if one of your accounts is currently signed in to any device or gaming console in your house and possibly made the purchase or subscription there.

In any case you can't find the right account, I suggest to directly contact your bank instead to file a dispute and cancel the payment permanently from that account.

You could've had automatic renewal for your xbox live account if anything that could be why your account is recently charged without you buying anything because it could be on automatic renewal

I have exactly the same problems, i getting charged for $0.99 multiple times without even buying anything

Hi Phoebe, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

It can be from an auto-renewal of your subscription. Please sign in to https://account.microsoft.com/billing/orders using all Microsoft accounts that you own, Phoebe.
