error code 80190826 comes up when i go to purchase the new gold membership for £2 a month. xbox support says its because the credit card billing adress used in the payment option does not match the billing address for the account. I have now changed it so that both are exactly the same but i'm still getting the same error code when i go to purchase the gold membership. im currently on hold to xbox support but god knows long that will take. Does anyone know how long this takes to solve itself or have any more ideas?
