About a month ago I received an email saying that my Xbox Live Gold membership would be automatically be renewed on the 23rd of April so I thought, fine I need a new one. It turns out that I used my old card which has now expired to purchase it last year and I now have a new card on the same account that I did not register with Xbox Live.
So then on the 23rd I got another email saying they had renewed my Xbox Live membership, I checked my account balance and they haven't removed any money, nor is any money due to be removed either. If I go to account management on my 360 it says that my next payment date is April 2008 so it seems I have just got another year for free

Now I'm in the dilemma of whether I should use the service as I haven't paid for it, as it could technically be seen as theft. What do you guys reckon?
