I have the same problem. I cancelled the auto-renewal for the Flexible Plan because I only needed a few photos for this month. And then in less than a month, they charged my credit card with a hundred dollar purchase which I didn't make! And when I contacted them, they replied that I purchased it through "a special promo offer 100 for $100 which originally cost $299 either from the website banner or from the email newsletter". Which I didn't really do since I was so busy on the day it was purchased and would be impossible for me to do on that day.
