Ran into a little bug here with billing for premium memberships. Short version: Giant Bomb tried to auto-renew my premium membership using a card that had recently been stolen online (to buy $8,000 plane tickets - what a nightmare) and canceled. I received an email alerting me to this, so I logged in and changed the card. That was 9/26/13 - now on 10/24/13 I just logged in and was not premium, and could not look at my billing history. After looking through my own card history, I determined I was never charged for the Premium renewal even though I updated my card information, so I just "upgraded" today. Just thought it was weird that I updated my billing info and it still didn't go through.
@meepasaurus: @gnsdemon: @rivalscho0ls: The bug with updating payment information should've been fixed earlier this month. Feel free to get in touch at firstname.lastname@example.org for specific billing issues, though; I'm loathe to discuss anything here about people's billing issues.
This just happened to me right now... I've travelled for a month and did not login. Today I came back and when I logged back in I'm not Premium anymore. I updated the billing information, confirmed my subscription payment but I still see ads. This is a very strange bug. My billing history was empty too.
