Hi fernandodel moral,

You can turn of auto-renewal by following the Cancel recurring subscription charges. You
will still be able to access your subscription until it runs out.

To see if you are eligible for a refund on any remaining days of your subscription, please see the Request
an Xbox digital product refund support page and follow the link to Request a refund

Hope this helps

you can try and get a refund on the remaining days left of your subscription when you cancel
