friend of mine just paid the $1 before adding any months, even tho I explained how to do it like 3 times. Is there any way to reverse it so he can add the time before the convert? #fail
Check the slickdeals thread. Some people mentioned being able to either cancel their ultimate or contact MS support to have them cancel it. This wild put your friend back to silver so they would lose any prepaid amount they had, but sounds like it might be worth it for them.
