Support Number For Partial Refund?

You would need to continue working with phone or chat support. They are the only ones who can deal with billing issues, however, they usually won't issue a partial refund for cases like this.

A mod removed the case number because those actually should not be posted on the forums. Those numbers are only used by phone and chat support and forum support does not have access to that information.

You should work for Microsoft support...Microsoft's system should be able to tell the difference between a partial refund and a chargeback. I did not report the charge as fraudulent, I requested a partial refund due to incorrectly charged tax and was refunded
$2.70, not the entire purchase price.

You would have to contact support and speak to billing to see if they can issue a refund like that, but generally they don't issue partial refunds.

I don't belive they can refund partial months, if you want to cancel your account you can contact xbox phone support and they can cancel and remove payment options.

The number for the american phone support is 1-800-4MY-XBOX.

If you do not live in america and would like the number for your country of residence please post it below and i will get it to you as soon as possible.

If your paid until September you can get a partial refund (pro-rated) for the remaining time left on the account. You will need to contact Microsoft via their customer service telephone number for this refund for any remaining time where they will be able
to tell you exactly what you'd be getting refunded for.
