Beware!!! I signed up for monthly payments to an annual subscription and Adobe tried to make me pay £100 after using the software for one month. No other software subscription does this . It's absolutely absurd. The first person I spoke to about this had exactly the same experience with Adobe. Sort this out - you can't rope people into a year's worth of monthly payments with just a couple of clicks. It costs Adobe absolutely nothing to cancel someone's subscription - nothing other than a scam!
when you subscribed did you select the plan with the lower monthly cost (that has a one year obligation) instead of selecting the monthly plan that costs more per month but allows you to cancel at any time?
