I got rather annoyed a few months ago that NV3 don't send a reminder to you that its due, I had the same issue with Kogan recently , they charged me $99 for a years premium account as I must have accidently ticked a box when ordering something, they did not let me know that their 'free 'trial was over, and it would have renewed automatically forever if I hadn't cancelled it. I was still stuck with the current subscritpion, but to give them their due they did return it to me when I complained. I'd do a direct debit and pay monthly if I were you.
