Hello!

My name is Dérek, I'm an independent platform consultant and I'm grateful for the opportunity to help you.

FlameszONice, Subscription upgrade is charged the full amount again, friend.

In this way, your past signature will be added to the new one, respectively.

But there really is no way to pay only the difference amount.

I remain at your disposal if you have any further questions.

thanks for the awnser, i thought that i could pay it mensaly with the microsoft balance

You need to put a valid payment method in credit/debit card or PayPal as it is a subscription contract that renews after the introductory period.

because the offers are directed to new people so that it helps them get started on their xbox. People who are existing members don't need these offers as they have already been subscribed to this service.
