20 euro was taken from my Microsoft account today for xbox live without that I wanted it now but I want my money back how could I do it and what do I have to do so that it no longer pays.
You can't do anything about that, it's not Microsoft's responsibility. Just cancel earlier next time.
To end the subscription go to:
Settings
account
Subscriptions
then you choose the right one and cancel it
If you have an subscription there you can easily end it by going to the store there should be Xbox live somewhere and there you should be able to finish that hope I could help you
Will I get the money if I end the subscription now or do I have to do it so that it is no longer deducted because I don't want my 20 euro to go away now
Your 20 euro are gone now. If you end the subscription you are only preventing something like that from happening again
