Switch to Xbox Ultimate for same price

Hi Derek, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

Just a friendly reminder though that there is no option for us users to undo subscribing to a subscription. Which means that you can try to cancel the subscription but getting the same promotion is not guaranteed as it is usually for first time users only.

Technically you're not. Gold and Game Pass are converted into Ultimate based on price, not based on the time. The price for 4 months of Ultimate is the same price as 12 months of gold. If you want to use the full 12 months of just Gold, you would need
to cancel Ultimate or wait for your Ultimate subscription to expire and then add the 12 months.

It should have converted as 4 months of Ultimate, not just 3 months. The conversion is based off the price, not the length of time. The price of a 12 month Gold subscription is the same price as 4 months of Ultimate. So you don't receive a credit.

I have ultimate, it's basically the same price as buying live and gamepass separately

The 14.99 is just the regular price of Ultimate, you don't get a discount for adding more time, the time is just converted into Ultimate. Gold and Game Pass are converted based on price rather than time. So the price of a 12 month subscription of gold
or game pass is the same price as purchasing 4 months of Ultimate. So since you added the 12 months of Gold before you Ultimate ended, it was automatically converted to Ultimate for 4 months. At the end of the 4 months, you would either need to renew Ultimate
(the 14.99 per month) or you can go back to just Gold after the Ultimate ends.
