When you signed up for your subscription you agreed to these terms.
This offer is for new Adobe Stock customers only and cannot be combined with other offers. This plan entitles you to Standard licenses only. One offer per Adobe Stock customer. Service begins from the moment that you activate this trial period by submitting your payment details. You will not be charged for the first month’s billing cycle. You’ll be charged the rate stated above, plus applicable taxes (such as value added tax when the stated rate doesn’t include VAT), every month starting with the second month’s billing cycle for the duration of your first annual contract. If the applicable VAT rate (or other included tax or duty) changes during your one-year term, the tax-inclusive price will adjust accordingly. Cancellations can be made any time by visiting your Manage Account page or by contacting Customer Support in your region. If you cancel during the first month billing cycle, your credit card will not be charged and your service will continue until the end of that first month’s billing cycle. If you cancel within 14 days after the beginning of the second month’s billing cycle, you’ll be fully refunded. If you cancel the service after the 14th day after the beginning of the second month’s billing cycle, you’ll be charged 50% of your remaining contract obligation and your service will continue until the end of that month’s billing period. After the first year, your contract will renew automatically on your annual renewal date until you cancel and you will be charged the rate stated at the time of purchase every month for the duration of each annual renewal term subject to the cancellation policies above. We’ll always notify you of your renewal, and any change in renewal rates, beforehand. Unused downloads from a monthly allowance of your annual plan accumulate and carry over for up to 12 consecutive billing cycles only if you have renewed the Adobe Stock subscription without letting it lapse and without repacking it with a lesser value subscription. Unused downloads (A) are subject to a cap of a maximum of twelve times your monthly allowance; and (B) automatically expire on a rolling basis 12 monthly billing periods after the date when they were first allocated. When your subscription ends, you will forfeit all rights to any unused downloads.
I think you already did. This is a public use to user forum. Good luck, but I have a feeling all you will accomplish is to show that you don't read what you agree to. 😉
Not saying I agree with the way it's done. But that is the way it is.
