I have an automatic monthly subscription to xbox live, how can I cancel this? On the website there seems to be no option to do so.

I have an Xbox 360 and treated myself to a classic original Xbox game (Spiderman 2). Typically, my Xbox Live subscription has just run out and I’m being told I need a media update to play the game. Is there any way of obtaining this update without having to spend £30 again?

I’d like to use a credit card, gift card or PayPal to purchase an XBox Live subscription. However, I’d prefer to not have to wait for the card to come via mail and I don’t really want to go to the store to purchase it either. Instead, I’d just like to purchase the code online and have it e-mailed to me once I pay. Does anyone know a website that will allow me to make this transaction?
