Wow, I don't know what to say. I don't see why if you called multiple times, and spoke to multiple people that said it was canceled, I don't know why it wouldn't be canceled.
Perhaps they have an "auto-cancel" order in the system to cancel your subscription on the 31st. Your system still thinks it will renew until that order goes through. Just a possibility. Either way, I have always had great response from their customer service. I even got MS Points refunded for purchasing an Xbox Live Arcade game, and then it went free a short while later for some promotion. I called and said I paid for it, but would have rather gotten it for free, so they refunded me the 800 MS points.
If it does end up charging you again, I'd call them until you get an absolute certain answer that your account was canceled and that you are not responsible for the charges.
