No there is only a charge for 0 sek but This morning i got a massage saying i bought game pass ultimate for 155kr

Also I was just charged yesterday April 9 2022 for XBOX game pass ultimate.

I'm talking about a one month's worth of regular game pass being upgraded to ultimate if I just bought regular game pass 3 days ago and changed my mind that I wanted to upgrade to game pass ultimate why wouldnt they just charge me the difference which if regular game pass is 12 dollars after tax and ultimate is 18 why wouldnt I just be charged 6 dollars or why cant they cancel the regular game pass charge or refund it and charge me the 18 for the ultimate instead ..itd would be absolutely dumb to of just paid 12 dollars three days ago for regular game pass and then if I want to upgrade be charged a whole new 18 dollars to upgrade

If you pre-ordered from Xbox, then the game would have gone on your account. You would not have got a code. The receipt would have been sent to your email, so check your junk/spam folders, as it may have gone in there.

Just q quick edit to say that your Gme Pass Ultimate code would be sent by Xbox message after full payment for the game is taken.

Quoting from the EA FC Xbox Page "Xbox Game Pass Ultimate Codes will be delivered via Xbox system message after full payment is received. Redeem at "http://www.microsoft.com/redeem" by 1 January 2024. Valid for new Xbox Game Pass members only. Valid payment method required. Unless you cancel, you will be charged the then-current regular membership rate when the promotional period ends. Limit: 1 per person/account. Subject to the Microsoft Services Agreement, Game Pass terms and system requirements at: xbox.com/subscriptionterms. Available in all Game Pass Ultimate regions except Russia see "https://www.xbox.com/regions"
