Kaila,
I would like to let you know that under the 10 images a month(one-year) plan, the first month is a trial one(free), however, 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 duration of your first annual contract.
For more information, you may refer to Legal subscription terms | Adobe
Also, I see you have contacted our support team and as per your request your Stock subscription has already been cancelled.
Hope this has resolved your issue.
Please let us know if you have any additional questions so that we can further assist you.
Regards
Twarita
