12 Month Game Pass ultimate "converted" to about 4 months of game pass without notifying me?

It didn't come with 4 months of Ultimate, it converted the Gold you added to 4 months of Ultimate. If you already have Ultimate on your account and you add a standard Gold or Game Pass code, it converts the time to Ultimate (since Ultimate already includes them) at a conversion rate based on the price rather than time. So the 12 months of Gold was converted to 4 months of Ultimate since a 12 month Gold is equal in price to Game Pass Ultimate.

It means that the time you got left on those suscriptions will be automatically converted to Ultimate Areeb.

Here is the convertion ratio:

1 month of Gold = 20 days of Ultimate

3 months of Gold 50 = days of Ultimate (1+ month)

6 months of Gold 79 = days of Ultimate (2+ months)

12 months of Gold 4= months of Ultimate

24 months of Gold 8= months of Ultimate

1 month of Xbox Game Pass (Console Games)= 20 days of Ultimate

3 months of Xbox Game Pass (Console Games)= 2 months of Ultimate

6 months of Xbox Game Pass (Console Games)= 4 months of Ultimate

12 months of Xbox Game Pass (Console Games)= 5 months of Ultimate

24 months of Xbox Game Pass (Console Games)= 10 months of Ultimate

I bought a 12 month card and it forced me to convert it to 4 months of ultimate game pass which is not what I wanted

I had 17 days left of game pass ultimate I decided to buy a 12 month Xbox live Gold card and a 3-month game pass ultimate card put in the 12 months first then the 3 months game pass ultimate card so that the 12 months would convert to game pass ultimate as well. Instead it only gave me 8 months game pass ultimate total as stated above.

If you add standard Gold/Game Pass while you have Game Pass Ultimate, the subscription is converted to Ultimate as well. The time is converted based on price rather than time so 12 months of Gold would have been converted to 4 months of Ultimate.
