Opendiary fraud

I am a bit upset as last night I subscribed for the yearly subscription for opendiary and said it was 39$ and when I looked at my credit card statement I was charged $55.05 so I guess my mistake because I am guessing it was us funds rather than CAD. However, after seeing the charge I cancelled my yearly subscription because I can’t afford to pay $55 for the yearly subscription ad didn’t want to wait until I forget to cancel later on. I had no idea that cancelling my subscription that I already paid $55 for For the entire year would Put me back to the limits of free subscription. I do not think it’s right for me to be charged $55 for having an upgraded subscription for just one day. I can now no longer post until waiting a certain time nor can I add photos. The subscription I paid for was for one year so why even if I’ve cancelled it am I not given the same options that I paid for? I paid for a yearly subscription and cancelled it so I wouldn’t forget to cancel later and now my membership is right back to free membership access. I don’t get it. So they gonna charge me $55 for just the one day of being able to post multiple times and add photos for the one day I had this before cancelling. I was willing to pay that mulch for the year but thought by me cancelling it meant that in a years time they wouldn’t recharge me. This isn’t right
