Branching to a new discussion,
Sorry to hear that.
I did go through your account details and noticed that you have Adobe Stock 10 images a month (one-year) plan which was purchased on 31st January 2018.
Currently, your subscription has been suspended due to payment issues and that is the reason you are unable to get the 'cancel option'. Please contact our support team Support FAQ: How can I contact Adobe for support? for further assistance.
Feel free to update this thread in case of any additional questions.
